Compressor electric motor, compressor, refrigerating cycle device, and compressor electric motor manufacturing method

An aluminum wire (62), which is an electric wire used in an electric motor (40) of a compressor (12), is wound around a copper wire (63), which is another electric wire, while being spaced in a length direction. The portion around which the aluminum wire (62) is wound is brazed by a brazing material (64) containing a flux. The aluminum wire (62) and the copper wire (63) are thereby joined each other to form an electric wire joint portion (65a). An insulating paper (61) is attached to the electric wire joint portion (65a). The inner surface of the insulating paper (61) is brought into contact with the surface of the electric wire joint portion (65a) to which flux residues adhere. 作为压缩机(12)的电动机(40)的电线的铝线(62)在长度方向隔开间隙而卷绕于作为其它电线的铜线(63)。卷绕有铝线(62)的部分通过含有焊剂的硬钎料材料(64)而被硬钎焊。由此，铝线(62)与铜线(63)相互被接合，形成电线接合部(65a)。绝缘纸(61)安装于电线接合部(65a)。绝缘纸(61)的内表面与附着有焊剂的残渣的电线接合部(65a)的表面接触。
