    • A method for pressure bonding metal members by utilizing eutectic reaction comprising the steps of bringing two metal members of dissimilar metals to be bonded into contact with each other under a predetermined contacting pressure P.sub.1 lower than the plastic deformation pressures of the metals of the two members and heating the contacting surfaces of the two members to a temperature lower than melting point temperatures of the metals and not lower than the eutectic temperature thereof to produce a liquid of eutectic composition by eutectic reaction between the surfaces of the two members to be bonded, applying an upset pressure P.sub.2 higher than the contacting pressure P.sub.1 to the surfaces to be bonded to squeeze out the liquid from the contacting surfaces of the two members to outside, and cooling the bonded surfaces of the two members. When the members to be joined by pressure bonding are of the same metal, an insert comprising an element undergoing eutectic reaction with the metal of the two members is interposed between the surfaces of the two members to be bonded.
