Abstract

A medical coaxial connector includes: an internal conductor configured to be electrically connected to an other-side inner conductor when the medical coaxial connector is connected to an other-side medical coaxial connector; an outer conductor electrically connected to the inner conductor, formed in a tubular shape surrounding the inner conductor, and configured to be electrically connected to an other-side outer conductor when the medical coaxial connector is connected to the other-side medical coaxial connector; and an insulating body that is placed on inner periphery side of the outer conductor and formed in a cylindrical shape surrounding the inner conductor. The insulating body is configured to be placed on inner periphery side of the other-side outer conductor and a leading end of the insulating body in a connection direction toward the other-side coaxial connector is configured to protrude more in the connection direction than the inner conductor.
