However, in the conventional coaxial connector described above, there is almost no guide for the outer periphery of the outer conductor portion 16A during insertion and removal. Therefore, the outer conductor portion 16A tends to be inserted or removed obliquely to the axis of the plug fitting hole 9, and therefore always gives a large displacement to one of the contact pieces 12. Therefore, by repeating insertion and removal, the contact piece 12 becomes fatigued, making it difficult to maintain a desired contact pressure, resulting in a problem in that the reliability of the connection between the external conductor parts decreases.
