To provide a joining method which can be used for joining various materials and can maintain high joining strength by relaxing stress generated between different kinds of materials.
The joining method comprising joining a first member 2 composed of a material having transparency to a laser beam and a second member 4 composed of a material different from the first member 2 comprises the steps of inserting an adhesive sheet 3 between the first member 2 and the second member 4, wherein the adhesive sheet 3 is composed of an elastomer having a storage modulus at 20°C of 0.05-500 MPa and has a thickness of 20-1,000 μm and irradiating a laser beam L onto the first member 2 to melt the adhesive sheet 3 to join the first member 2 and the second member 4.
