Abstract
In a method of producing a composite insulator having a core member, end fitting members fixed to both end portions of the core member, and an overcoat member including a sheath portion formed on an outer surface of the core member and shed members, the overcoat member and the end fitting member are connected by curing. Moreover, a clamping operation is performed or a packing member is used for preventing a flow of an overcoat forming material into a seal portion. In this manner, it is possible to improve a seal performance of a connection boundary between the end fitting member and the overcoat member.
