Abstract

An object of the present invention is to obtain a resin molded bushing which can easily perform positioning of an electric field relaxation shield in a switchgear. The resin molded bushing includes: an electric field relaxation shield which concentrically surrounds the outer periphery of an internal conductor made of conductor; a cast resin which covers the internal conductor and the electric field relaxation shield; and an elastic member which is disposed on the outer periphery of the electric field relaxation shield and is embedded in the cast resin. The height of the elastic member is equal to the thickness of the cast resin which covers the electric field relaxation shield.
