An object of the present invention is to provide an electric disc brake suitable for improving responsiveness. The electric disc brake includes: a rotation linear motion conversion mechanism configured to convert rotational motion of the rotary member into linear motion; a return spring configured to store torque for retreating the piston according to rotation of a rotary member; and a clutch configured to make a transition between a state in which the torque is able to be stored in the return spring and a state in which storage of the torque in the return spring is deterred. The clutch includes: a first disc and a third disc configured to rotate together with the rotary member, and a second disc disposed between the first disc and the third disc. The return spring has one end portion coupled to the caliper body and another end portion coupled to the second disc.
