To connect dissimilar materials to each other while suppressing heat effects.SOLUTION: A method for connecting dissimilar materials comprises the steps of: joining a first member 100 and a second member 110 formed from a different type of material than the first member 100 and provided with a through hole 111 to each other by bringing a tip end portion 122t of a columnar portion 122 into contact with the first member 100 while inserting, into the through hole 111, the columnar portion 122 in a joining member 120 that includes a head portion 121 formed from the same material as the first member 100 and having a diameter larger than that of the through hole 111, and the columnar portion 122 protruding from the head portion 121; and connecting the tip end portion 122t of the columnar portion 122 and the first member 100 by applying a supersonic vibration.SELECTED DRAWING: Figure 3 【課題】異種材料を、熱影響を抑制しつつ互いに接続する。【解決手段】異種材料の接続方法は、第１部材１００と、第１部材１００とは異なる種類の材料から形成され、貫通孔１１１が設けられた第２部材１１０とを、第１部材１００と同じ種類の材料から形成され、貫通孔１１１の径より大径の頭部１２１および頭部１２１から突出した柱状部１２２を含む連結部材１２０における、柱状部１２２を貫通孔１１１に挿通しつつ柱状部１２２の先端部１２２ｔを第１部材１００に接触させることにより、互いに連結させる工程と、超音波振動を印加することにより、柱状部１２２の先端部１２２ｔと第１部材１００とを接合する工程とを備える。【選択図】図３
