Abstract
Provided are a method for joining dissimilar materials and a joint of dissimilar materials. The method for joining dissimilar materials includes: a step of forming a first recess and a second recess that are engraved in a slanted direction at mutually different angles with respect to a surface by irradiating laser light on the surface of a first member; and a step of causing a portion of a second member having a lower melting point than the first member to melt and flow inside each of the first recess and the second recess and solidify, thereby causing the portion of the second member to engage with each of the first recess and the second recess and joining the second member to the surface of the first member.
