Coaxial connector

A coaxial connector including, as a pair of male and female connectors, a first connector and a second connector each including a contact portion that includes:

• a rod-shaped center conductor;
• and a tubular outer conductor that surrounds a circumference of the center conductor almost entirely in a lengthwise direction thereof, the contact portions of the connectors electrically connected to or disconnected from each other by being fitted to or removed from each other only by an operation of sliding the connectors along an axis of a line on which the connectors are arranged,
• wherein the contact portion of at least one of the connectors includes a contact-section portion in which the center conductor, the outer conductor and an insulator are formed with no gap disposed therebetween while the center conductor and the outer conductor are disposed across the insulator to be away from each other at a predetermined distance, the contact-section portion being attached to a housing included in the connector,
• a plurality of slots each extending in an axial direction are provided on a base-end portion side of the outer conductor in the contact-section portion, the base-end portion side being a side to be attached to the housing, and
• the plurality of slots form base-end-side supporting pieces allowing deformation in a radial direction.
