Abstract
According to an aspect, a force sensor includes: a first electrode; a second electrode; a first conductor facing the first electrode in a first direction; a second conductor facing the second electrode in the first direction; a first elastic member and a second elastic member arranged between the first electrode and the first conductor; and the first elastic member arranged between the second electrode and the second conductor. The first elastic member and the second elastic member have degrees of compression with respect to force thereon that are different depending on temperature.
