PROBLEM TO BE SOLVED: To provide a joining structure which suppresses a malfunction caused by the generation and growth of spatters or burrs which are generated at joining without complicating or enlarging a device for joining joined members, and a cooler including the joining structure.SOLUTION: A joining structure comprises a first joined member 1 having a first main surface 1s, and a second joined member 2 having a second main surface 2s. The first joined member 1 and the second joined member 2 are connected to each other in a joining part 3. At least either of the first or second joined members 1, 2 includes a thin-thick part 5 in the joining part 3. A thickness with respect to a direction which intersects with the main surfaces 1s, 2s in the thin-thickness part 5 is thinner than a thickness of a heavy-thickness part other than the thin-thickness part 5.SELECTED DRAWING: Figure 4 |
