Abstract
Provided is a capacitance sensor including: a first electrode including a first region gradually larger in height with respect to a width direction parallel to a first direction in parallel with a second direction orthogonal to the first direction, a second region gradually smaller in height with respect to the width direction, and a third region causing the first and second regions to be opposed; a second electrode opposed to the first region in the second direction, and gradually smaller in height with respect to the first direction in parallel with the second direction; a third electrode opposed to the second region in the second direction and gradually larger in height with respect to the first direction in parallel with the second direction; and a support body supporting electrode groups including the first to third electrodes while connected via the third region, and arranging those groups along the second direction.
