A connector 10 includes an inner conductor terminal 11, an outer conductor terminal 13 for covering an outer periphery of the inner conductor terminal 11, and a dielectric 12 arranged between the inner conductor terminal 11 and the outer conductor terminal 13. The inner conductor terminal 11 includes a tubular terminal body 20 extending in a front-rear direction and projections (e.g. front projections 21 and rear projections 22) provided on the terminal body and to be locked to the dielectric 12. A plurality of the projections are provided at an interval in the front-rear direction.
