A pump (1) including an impeller (11) having blades (111) on its outer periphery and a rotor magnet (112) on its inner periphery, a motor stator (12) placed facing the rotor magnet (112), a pump casing (13) for partitioning between the impeller (11) and the motor stator (12) and having formed in it a recess (133) for receiving the motor stator (12), and an electronic circuit board (15) having mounted on it a drive IC (41) for supplying an electric current to the stator motor (12). The electronic circuit board (15) is placed so that the drive IC (41) mounted on it faces the motor stator (12) and is fixed to the pump casing (13).
