Sensor

A sensor, comprising:

• a base including a first base region and a second base region;
• a first detection unit including a first detection element, the first detection element including a first resistance member, a first conductive member, and a first insulating member, at least a part of the first insulating member being between the first resistance member and the first conductive member, a first gap being provided between the first base region and the first detection element, the first detection element having a first area in a plane crossing a first direction from the first base region to the first detection element;
• and
• a second detection unit including a second detection element, the second detection element including a second resistance member, a second conductive member, and a second insulating member, at least a part of the second insulating member being between the second resistance member and the second conductive member, a second gap being provided between the second base region and the second detection element, the second detection element having a second area in the plane, the second area being smaller than the first area.
