Abstract

A resistive element including a main body portion, and first and second terminal portions with different shapes that are provided at opposite ends of the main body portion in the long-side direction. At least one side portion of the main body portion in the short-side direction has a protruding portion.

First claim

What is claimed is:

1 . A resistive element comprising:
a main body portion; and first and second terminal portions provided at opposite ends of the main body portion, wherein at least one side portion of the main body portion has a protruding portion.

2 . The resistive element according to claim 1 , wherein
opposite side portions of the main body portion have a first protruding portion and a second protruding portion, respectively, and the first protruding portion and the second protruding portion have different shapes.

3 . The resistive element according to claim 2 , further comprising a covering material that covers a metal material of the main body portion.

4 . The resistive element according to claim 3 , wherein one of an end portion of the first protruding portion or an end portion of the second protruding portion is not covered with the covering material.

5 . A method for manufacturing a resistive element, the resistive element including a main body portion, first and second terminal portions provided at opposite ends of the main body portion, and a protruding portion provided at least on one side portion of the main body portion, the method comprising:
preparing a sheet-like or hoop-like plate-shaped body made of a metal material; forming a hole for defining a peripheral shape of the terminal portions in the plate-shaped body, and forming a first coupled portion that is coupled to the plate-shaped body on a side portion of the main body portion; and cutting the main body portion at the first coupled portion, thereby forming the protruding portion on the side portion of the main body portion.

6 . The method for manufacturing a resistive element according to claim 5 , further comprising adjusting a resistance value of the main body portion by adjusting an amount of protrusion of the protruding portion, the amount of protrusion being dependent on a cut position at the first coupled portion.

7 . The method for manufacturing a resistive element according to claim 6 , wherein
the main body portion has a second coupled portion formed on another side portion thereof, and the method further comprises cutting the main body portion at the second coupled portion.

8 . The method for manufacturing a resistive element according to claim 7 , wherein
the second coupled portion has at least one hole formed therein in advance, and the method further comprises cutting the main body portion at a portion where the hole of the second coupled portion is formed, thereby forming a plurality of protruding portions on the other side portion of the main body portion.
