The present invention provides a further miniaturized coaxial connector. A coaxial connector includes a contact by three-point contact, a housing including a first and a second connection base, and a shell including a cylindrical portion accommodating the first connection base and an extension portion accommodating the second connection base. The contact disposed inside an accommodation space on the first connection base, includes three terminals including a pair of fixed terminals and a movable terminal that are erected from a tip end side of a metal plate. The pair of fixed terminals are located at a set of vertices among vertices of a virtual equilateral triangle inscribed in a mating contact, the movable terminal is located at the other vertex of the virtual equilateral triangle, and a contact surface of the movable terminal is disposed in a state of facing an intermediate portion of the pair of fixed terminals.
