A metal member 1 and a resin member 2 are brought into contact with each other without interposing a resin layer between the metal member 1 and the resin member 2. A rotation tool 10, which is being rotated, is pressed against the surface 1a of the metal member 1 in an inclined state so that the inclination angle of the axis Q of the rotation tool 10 relative to the normal line P of the surface 1a of the metal member 1 satisfies the condition of 0<5. This applies friction energy to the metal member 1 to join the metal member 1 and the resin member 2.
