Abstract
In a joining method for joining a first plate material and a second plate material by screwing a self-tapping screw from one direction in a state where the first plate material and the second plate material are put on top of each other, a recessed portion is formed in at least one of the first plate material and the second plate material, and in a state where the first plate material and the second plate material are put on top of each other such that the recessed portion is opened in a contacting face between the first plate material and the second plate material, the self-tapping screw is screwed from the one direction. When the self-tapping screw penetrates through the first plate material due to the screwing of the self-tapping screw, an excess part generated from the first plate material flows into the recessed portion.
