A mammography apparatus includes: a moving unit that moves a compression plate in a compression direction in which the breast is compressed and a decompression direction in which the breast is decompressed； a radiation source； a pressure sensor that is used to measure a compression pressure which is a compression force of the compression plate per unit area； and a control unit that controls the moving unit such that the compression plate is moved to a first position where the compression pressure measured by the pressure sensor is a first compression pressure in the compression direction and is moved to a second position where the compression pressure measured by the pressure sensor is a second compression pressure in the decompression direction and performs control such that radiation is emitted from the radiation source in a state in which the compression plate is located at the second position.
