Abstract
A method for producing a joined body of different materials. In the joined body, a plurality of resin layers may be joined together and a resin layer may be joined with a metal layer. A joined body of different materials.
Claims10
A method for producing a joined body comprising different materials joined together, the method comprising the steps of:
- preparing a metal substrate comprising two or more etched grooves on a surface thereof and burrs provided adjacent to each of the two or more etched grooves;
- sequentially laminating a first resin layer and a second resin layer on the surface of the metal substrate, thereby producing a laminate;
- and
- irradiating a surface of the second resin layer with a laser,
- wherein the first resin layer has a light transmittance of 20% to 70% at any one wavelength selected from a range of 800 nm to 1,100 nm, and
- the light transmittance of the first resin layer at the any one wavelength is lower than a light transmittance of the second resin layer at the any one wavelength.
