Abstract
Provided is a method of manufacturing a heterogeneous material joined body, the method comprising irradiating a surface of a glass layer with a first laser to form two or more etched lines on the surface of the glass layer; providing a resin layer on the surface of the glass layer having the two or more etched lines; and irradiating the surface of the glass layer with the resin layer with a second laser to fill the etched lines and the surface of the glass layer with the resin layer and join the resin layer and the glass layer, wherein the glass layer having the two or more etched lines is irradiated with the second laser in a direction from the glass layer to the resin layer with focus on the surface of the glass layer which is in contact with the resin layer.
