Claim 0:
1. A dissimilar material solid phase bonding method which is a solid phase bonding method for bonding one member and other member, characterized in that:
the one member and the other member have different compositions;
the one member and the other member are brought into contact with one another by way of an insert material to form a first interface to be bonded, at which the one member and the insert material are in contact with one another, and a second interface to be bonded, at which the other member and the insert material are in contact with one another;
the temperature of the first interface to be bonded and the second interface to be bonded is raised by means of frictional heat due to sliding between the one member and the insert material and between the other member and the insert material, and/or by electrical heating;
a first bonding pressure is applied substantially perpendicular to the first interface to be bonded;
a second bonding pressure is applied substantially perpendicular to the second interface to be bonded; and
the first bonding pressure and the second bonding pressure are set to different values,
wherein the first bonding pressure is set to a value equal to or higher than a yield stress and equal to or lower than a tensile strength of the insert material and the one member at the first temperature, and
the second bonding pressure is set to a value equal to or higher than a yield strength and equal to or lower than a tensile strength of the insert material and the other member at the second temperature.
