Abstract
A piezoelectric sensor includes an elastic body having a first surface, a regulatory section which is disposed at a position where the regulatory section faces the first surface of the elastic body, and which is configured to limit a deformation of the elastic body, and a first piezoelectric element which is partially fixed to the regulatory section, and which deforms in accordance with the deformation of the elastic body, wherein the first piezoelectric element outputs a voltage signal which increases and decreases from a reference voltage in accordance with a direction of the deformation.
