Abstract

The electric component includes first and second members 30 and 40 , at least one of which being used as an electric conductor. The first member includes a bus bar 31 and a resin member 32 for covering the bar and has a predetermined area where they expose to the exterior. The second member has an exposing portion where the surface of the aluminum wire 44 exposes and the exposing portion faces portions (H1, H3) where the bar 31 exposes to the exterior at the predetermined area. The first and second members are supported by a housing 10 including a resin at least having a part exposing to the exterior. In this electric component, the first member is configured such that the contact angle of the water droplet relative to the surface of the resin member 32 within the predetermined area is smaller than or equal to 70 degrees.

First claim

The invention claimed is:

1. An electric component comprising:
a first member which includes a first metal member and a cover member for covering said first metal member and is configured to have a predetermined area where only said first metal member and said cover member expose to the exterior; and
a second member which includes a second metal member and is configured to have an exposing portion where a surface of said second metal member exposes, and
wherein a portion where said first metal member exposes to the exterior at said predetermined area and said exposing portion of said second metal member face each other and at least one of said first and second metal members is used as an electric conductor, and
wherein said cover member is configured such that a contact angle of a water droplet relative to a surface within said predetermined area is smaller than or equal to 70 degrees.

2. The electric component as set forth in claim 1 , wherein said cover member is processed to have a surface roughness such that the contact angle of the water droplet relative to said surface within said predetermined area is smaller than or equal to 70 degrees.

3. An electric component comprising:
a first member which includes a first metal member and a cover member for covering said first metal member and is configured to have a predetermined area where only said first metal member and said cover member expose to the exterior; and
a second member which includes a second metal member and is configured to have an exposing portion where a surface of said second metal member exposes, and
wherein a portion where said first metal member exposes to the exterior at said predetermined area and said exposing portion of said second metal member face each other and at least one of said first and second metal members is used as an electric conductor, and
wherein said cover member is processed to decrease a contact angle of a water droplet relative to a surface within said predetermined area.

4. An electric component comprising:
a first member which includes a first metal member and a cover member for covering said first metal member and is configured to have a predetermined area where only said first metal member and said cover member expose to the exterior;
a second member which includes a second metal member and is configured to have an exposing portion where a surface of said second metal member exposes; and
a housing which supports said first member and includes an insulating member and is configured such that a part of or an entirety of a surface of said insulating member exposes to the exterior, and
wherein a portion where said first metal member exposes to the exterior at said predetermined area and said exposing portion of said second metal member face each other and at least one of said first and second metal members is used as an electric conductor, and
wherein said cover member is configured such that a contact angle of a water droplet relative to a surface within said predetermined area is smaller than that relative to said surface of said insulating member exposing to the exterior.
