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.

Abstract: A biological information acquisition device includes a main body including a facing surface facing a living body when mounted, a first biosensor provided in the main body such that at least a portion of the first biosensor protrudes from the facing surface of the main body and including a first contact surface contactable with the living body, and an adhesive tape attached to the facing surface of the main body and having a thickness less than a protrusion amount of the first biosensor from the facing surface.
