Abstract

An infrared sensor includes: an infrared detecting device; a lens disposed above the infrared detecting device; an member that is disposed at a side of an upper surface of the lens and includes an opening; and a gap that intervenes between the member and the lens and has a wider range than the opening.

First claim

The invention claimed is:

1. An infrared sensor, comprising:
an infrared detecting device;
a lens disposed above the infrared detecting device;
a member that is disposed on an upper surface of the lens and includes an opening;
a gap that is disposed between the member and the lens and has a wider range than the opening; and
a package that houses the infrared detecting device,
wherein the package includes a window hole disposed above the infrared detecting device, and the lens is disposed so as to close the window hole.

2. The infrared sensor of claim 1 , wherein a width of the window hole is larger than a width of the gap.

3. An infrared sensor, comprising:
an infrared detecting device;
a lens disposed above the infrared detecting device;
a member that is disposed on an upper surface of the lens and includes an opening;
a gap that is disposed between the member and the lens and has a wider range than the opening;
a cover member disposed above the infrared detecting device; and
a package that houses the infrared detecting device and the cover member,
wherein the upper surface of the lens is positioned upper than an upper surface of the package.

4. The infrared sensor of claim 3 , wherein
the package has a window hole, and
a side surface of the lens is apart from the package.
