Abstract

A composite electrical insulator includes a metal fitting (3, 4) fixedly secured to a fiber-reinforced plastic rod (1) at one end thereof. The rod has a stress-relieved zone (8) situated opposite to the metal fitting (3, 4), and formed by a heat treatment of the rod (1) after an end portion of the rod (1) has been inserted into a bore (5) in the metal fitting (3, 4) and the metal fitting (3, 4) fixedly secured to the rod (1).
The heat treatment of the rod (1) is performed at a temperature which is not lower than a heat transition temperature of a matrix resin of the fiber-reinforced plastic material.
