To provide a terminal block for a rotary electric machine, capable of establishing both of stable holding of a power line of the rotary electric machine and suppression of surge voltage.SOLUTION: A terminal block for a rotary electric machine comprises: three bus bars 30, each of which is formed in a band-like shape, has a power supply terminal 31 on one end side in an extension direction of the band-like shape, and has a stator connection part 35 on the other end side; and a resin molding part 21, inside which the bus bars 30 are passed to hold the three bus bars 30 so as not to be relatively movable. The three bus bars 30 have an overlapping part 40 that is a section in which the three bus bars 30 are disposed so as to be overlapped with one another while being separated from one another in the thickness direction and is positioned inside the resin molding part 21. The resin molding part 21 holds the bus bars 30 in a state of the bus bars 30 being separated from one another by making resin material enter between bus bars 30 adjacent to each other in the thickness direction of the bus bars 30 at a position of the overlapping part 40 of the bus bars 30.SELECTED DRAWING: Figure 2 【課題】回転電機の動力線の安定的な保持と、サージ電圧の抑制とを両立することのできる回転電機の端子台を提供すること。【解決手段】帯状の形状で形成され、帯状の延在方向における一端側に電源端子３１を有し、他端側に固定子接続部３５を有する３つのバスバー３０と、内側にバスバー３０を通して３つのバスバー３０を相対移動不可に保持する樹脂成形部２１と、を備え、３つのバスバー３０は、３つのバスバー３０が厚み方向に互いに離隔しつつ重なって配置される区間であり樹脂成形部２１の内側に位置する重なり部４０を有し、樹脂成形部２１は、バスバー３０における重なり部４０の位置ではバスバー３０の厚み方向において隣り合うバスバー３０同士の間に樹脂材料が入り込むことにより、バスバー３０同士を離隔させた状態でバスバー３０を保持する。【選択図】図２
