Abstract
A sensor includes a base, and first and second resistance lines. The base extends in a direction intersecting with a central axis. The first resistance lines are arrayed in a circumferential direction on a surface of the base. The second resistance lines are arranged concentrically with the first resistance lines and between the first resistance lines in the circumferential direction on the surface of the base. In the first resistance lines, the number of regions of the resistance line along the circumferential direction is one or less, and the number of regions of the resistance line along a radial direction is one or less. The sensor is able to provide improved detection accuracy.

A sensor comprising:
- a base extending in a direction intersecting with a central axis;
- first resistance lines arrayed in a circumferential direction on a surface of the base;
- and
- second resistance lines arranged concentrically with the first resistance lines and between the first resistance lines in the circumferential direction on the surface of the base;
- wherein
- in at least one of the first resistance lines, a number of regions of the resistance line along the circumferential direction is one or less, and a number of regions of the resistance line along a radial direction is one or less;
- and
- the base includes a rotation angle detection sensor to detect a rotation angle of rotational motion.
