An infrared-detecting element includes: a substrate; a laminated body; an anchor coupling a part of the laminated body with the substrate and supporting the laminated body with a gap above the substrate; and an amplifier provided on the substrate and connected to at least one of the lower electrode and the upper electrode. The laminated body has a lower electrode, an upper electrode, and a piezoelectric film made of aluminum nitride which is provided between the lower electrode and the upper electrode and in which a c-axis is oriented almost perpendicularly to a film plane. The amplifier has a circuit performing conversion into voltage according to a charge generated in the laminated body.
