Abstract
A bioacoustic sensor includes a diaphragm including a contact surface contactable with a living body and a back surface, and being displaceable in a thickness direction, and a piezoelectric plate including a first surface facing the back surface of the diaphragm with a gap therebetween and a second surface on a side opposite to the first surface to convert the vibration of the diaphragm into an electric signal. The diaphragm is in contact with a center side portion of the first surface of the piezoelectric plate when viewed in the thickness direction, and a housing supports an outer side portion of the second surface of the piezoelectric plate when viewed in the thickness direction.
