PROBLEM TO BE SOLVED: To make diffusion welding possible in a high-pressure state for a plurality of joining members simultaneously. SOLUTION: The high-pressure diffusion welding equipment uses equipment having an electric power source 7 for generating a pulsed current or an AC current and a vacuum furnace or an atmospheric furnace with a mechanism for pressurizing joining members 10, 11 by means of an air or hydraulic cylinder 14 or the like. A heating element is installed on the outer periphery of the joining members and, using its radiation heat and heat transfer, diffusion welding is performed while the joining members 10, 11 are pressurized without making an electric current flow directly in the joining members.
