PROBLEM TO BE SOLVED: To provide a method of bonding different materials which can tightly bind different materials together and, further, does not require to change structures of parts of the different materials. SOLUTION: A method of bonding a metal material and a material different from the metal material together includes the steps of: forming a coated film by subjecting the metal material to surface treatment; applying a pressure-sensitive adhesive material onto the coated film; and performing injection molding of a plastic material to the surface having the coated film on the metal material and maintaining such a state as to be in the temperature range of 150 to 200°C and the pressure range of 32×10<SP>6</SP>to 47×10<SP>6</SP>Pa. It is preferable that a step of heating the pressure-sensitive adhesive material is further provided after the step of applying the pressure-sensitive adhesive material onto the coated film, and it is recommended to heat the pressure-sensitive adhesive material for 30 to 40 min at 60°C in the heating step.
