An image-pickup apparatus includes a lead screw, a moving member, an image-pickup element, a mirror member that is capable of rotating between a first state and a second state, an urging member, and a first abutment member configured to abut against the mirror member when the mirror member is in the first state. An engagement portion parallel to a rotational axis of the mirror member is protruded from the mirror member. The engagement portion is held by both ends of the urging member when the mirror member rotates between the first state and the second state. A first end of the urging member elastically deforms so as to be apart from the engagement portion when the mirror member abuts against the first abutment member.
