Camera side contact pins include a first camera side contact pin making contact with an accessory side contact holding portion in the first state and second camera side contact pins not making contact with the accessory side contact holding portion in the first state. Accessory side contact surfaces include a first accessory side contact surface making contact with the first camera side contact pin in the second state and second accessory side contact surfaces not making contact with the first camera side contact pin in the second state. A pitch between the first and second accessory side contact surfaces adjacent thereto is larger than a pitch between the second accessory side contact surfaces adjacent to each other.
