Claim:
1. An electric contact device that electrically connects a camera body to a lens unit, the electric contact device comprising: a flexible printed circuit board on which a conductive pattern is formed; a contact member that comes into direct contact with the flexible printed circuit board and is electrically connected to the conductive pattern, a surface of the contact member that comes into contact with the flexible printed circuit board being a curved surface; a base that includes a first hole holding a first end portion of the contact member so as to allow the first end portion of the contact member to be displaced between a protruding position where the first end portion protrudes and a retracted position where the first end portion is retracted; a biasing member that has elasticity so as to be extended and contracted between a first end thereof and a second end thereof, the first end of the biasing member biasing the flexible printed circuit board such that the flexible printed circuit board is bent along the curved surface of the contact member and comes into contact with a second end portion of the contact member; a support member that supports the second end of the biasing member; and a guide that is composed of a first groove formed on the base and a second groove formed on the support member and guides the extension and contraction of the biasing member.
