In the present invention, a metal composition in paste form is placed between a first joining member and a second joining member (placement step). Next, the metal composition at a normal temperature is heated, in accordance with a temperature profile, using a reflow device, etc., while being compressed in the thickness direction (heating step). The heating step is for carrying out a heat treatment satisfying S · P <u>></u> 15 (kK · s · N/m2) on the metal composition, the heat treatment being carried out during a time period t2-t1(s) from when the heating temperature rises to the Sn powder melting point or higher until the heating temperature falls to below the Sn powder melting point, where S (kK · s) is the amount of heat applied to the metal composition from a temperature range which includes at least the melting point of the Sn powder, and P(N/m2) is the pressure applied to the metal composition. |
