A piezoelectric sensor including: a piezoelectric sheet; a first ground electrode integrally laminated on a first side of the piezoelectric sheet and having a first cutout section; a signal electrode integrally laminated on a second side of the piezoelectric sheet and having a third cutout section; and a second ground electrode integrally laminated on the signal electrode so as to be electrically insulated from the signal electrode and having a second cutout section. The cutout sections of the signal electrode, the first ground electrode, and the second ground electrode are at least partially overlapped with one another in a thickness direction of the piezoelectric sheet. A portion of the piezoelectric sheet exposed from a portion where the cutout sections of the signal electrode, the first ground electrode, and the second ground electrode are overlapped with one another serves as an exposed section.
