Abstract: A welding method heats and pressurizes a contacting portion, where a first member and a second member made of resin are in contact with each other, by a pressing tool. The welding method has forming a step, forming a recessed portion, crushing a protrusion, and filling the recessed portion. The step is defined between the first member and the second member by providing the protrusion to the first member. The recessed portion is provided in a tip of the pressing tool. The protrusion of the first member is crushed in the recessed portion by being pressed toward the second member using the pressing tool. The recessed portion is filled with the molten portion of the first member and the molten portion of the second member such that a rim of an outer periphery of the recessed portion is dug into the first member and the second member.

Abstract: A method for producing a bonded body of ceramic and metal bodies includes stacking a ceramic body, metal body, gap layer capable of preventing oxidation and hindering heat conduction, first intermediate layer and second intermediate layer with the gap layer between the ceramic body and the metal body in the stacking direction. The first intermediate layer is between the ceramic body and gap layer, and the second intermediate layer is between the gap layer and metal body, linear expansion coefficients of the first and second intermediate layers being between those of the ceramic body and the metal body. Diffusion bonding is performed between the ceramic body and the first intermediate layer, and between the metal body and the second intermediate layer simultaneously. The gap layer is then removed from between the first and second intermediate layers. The first and second intermediate layers are then bonded to each other.

Abstract: The present invention provides a method of bonding ceramic and metal comprising the steps of bonding metal foils to a bonding surface of a ceramic matrix and a bonding surface of a metal matrix to be bonded and then heating so as to leave metal layers at the surfaces of the metal foils while forming diffusion layers with inclined linear expansion coefficients with materials of the metal foils diffused in them between the ceramic matrix and metal layer and between the metal matrix and metal layer, and making the respective metal layers which remain at the surfaces of the metal foils bond so as to bond the ceramic matrix and the metal matrix.
