Method for joining dissimilar metal pieces

This method for joining dissimilar metal pieces comprises: a preparation step for preparing a rivet, a plurality of metal members, a shank, and an electrode part provided at the tip of the shank; a sandwiching step of sandwiching the rivet and the plurality of metal members with a first electrode and a second electrode; and an embedding step in which the rivet is embedded into the metal member by applying pressure and energizing with the first electrode and the second electrode. The preparation step includes a step of preparing, as a first electrode and a second electrode, two electrodes satisfying a condition that a resistance value of the first electrode and a resistance value of the second electrode are less than or equal to a total value of a resistance value of the plurality of metal members to be bonded and a resistance value of the rivet. 异种金属件的接合方法具备：准备工序，准备铆钉、多个金属部件、以及柄和设置于柄的前端的电极部；夹入工序，利用第一电极和第二电极夹着铆钉及多个金属部件；以及埋入工序，通过利用第一电极和第二电极进行加压通电，使铆钉相对于金属部件埋入。准备工序包括如下工序：作为第一电极及第二电极，准备满足第一电极的电阻值及第二电极的电阻值为待接合的多个金
