Abstract

A method for manufacturing a joined body includes at least one first plate material, one second plate material, and a self-piercing rivet where a cylinder portion projects from a head. The method includes: a test step of plastically deforming the second plate material by a load in a plate thickness direction to measure physical value information of the second plate material; a setting step of setting a joining condition based on the physical value information by the test step; and a joining step of supporting a back surface of the second plate material having a front surface on which the first plate material is stacked with a die and driving the cylinder portion from the front surface side toward a concave portion provided in the die to join the first plate material and the second plate material together based on the joining condition set by the setting step.
