PROBLEM TO BE SOLVED: To provide a coaxial connector with improved impedance characteristics.SOLUTION: A coaxial connector comprises: an external conductor; a central conductor; an insulation member; and an annular metal fitting. The external conductor has: a substrate mounting part; a body part; and a communication hole for making the substrate mounting part and the body part communicate with each other. The insulation member is housed in the communication hole of the external conductor. The central conductor is supported by the insulation member and arranged inside the communication hole of the external conductor. The annular metal fitting has: a through-hole; and an opposite face, in a plane extending in a radial direction perpendicular to the axial direction, which faces at least part of the insulation member. The annular metal fitting is housed in the communication hole of the external conductor on the substrate mounting part side with respect to the insulation member. The central conductor, supported by the insulation member, penetrates through the through-hole of the annular metal fitting. The diameter of an air layer of the annular metal fitting in the vicinity of the opposite face is set to be greater than the diameter of the air layer of the annular metal fitting on a side spaced apart from the opposite face. |
