Coaxial connector

A coaxial connector that is attached to a coaxial cable, the coaxial cable including a first central conductor, an insulating body provided around the first central conductor and having a foam structure or a hollow structure, a first outer conductor provided around the insulating body, and an insulating film provided around the first outer conductor, the insulating film being removed at a distal end of the coaxial cable and the first outer conductor being exposed, the first outer conductor being removed at the distal end of the coaxial cable and the insulating body being exposed, the coaxial connector comprising:

• a housing including a cylindrical part having a central axis being substantially orthogonal to an extending direction of the coaxial cable, and a holding part extending from the cylindrical part along the coaxial cable;
• a bushing attached to the housing;
• and
• a socket located at a center of the cylindrical part in plan view in a direction in which the central axis extends, insulated from the housing by the bushing, and connected to the first central conductor,
• the holding part including
• a first crimp portion for holding the first outer conductor, and
• a second crimp portion for holding the insulating film,
• the second crimp portion having a protrusion at a surface which contacts the insulating film.
