CIRCUIT BOARD, CONNECTION STRUCTURE OF CONDUCTIVE MEMBER AND ELECTRIC COMPRESSOR

To increase the flexibility of connection of a conductive member with respect to a metallic circuit board.SOLUTION: A board 1 comprises a peripheral portion 22 where an electric circuit is formed, an isolation portion 21 to which a terminal 40 is fixed, and an insulating portion 30 that is interposed between a first side surface portion 22S and a second side surface portion 21S and couples the isolation portion 21 to the peripheral portion 22 and electrically insulates the isolation portion 21 from the peripheral portion 22. The first side surface portion 22S is joined to the insulating portion 30, and includes a first outer peripheral surface 21a, a second outer peripheral surface 21b and a third outer peripheral surface 21c each subjected to alumite treatment to increase bonding strength with the insulating portion 30. The second side surface portion 21S is joined to the insulating portion 30, and includes a first inner peripheral surface 22a, a second inner peripheral surface 22b, and a third inner peripheral surface 22c each subjected to an alumite treatment for enhancing the bonding strength with the insulating portion 30.SELECTED DRAWING: Figure 1 【課題】金属製の回路基板に対する導電部材の接続の自由度を高める。【解決手段】基板１は、電気回路が形成される周辺部２２と、端子４０が固定される隔離部２１と、第１側面部２２Ｓと第２側面部２１Ｓとに挟まれ、隔離部２１を周辺部２２に連結すると共に隔離部２１を周辺部２２に対して電気的に絶縁する絶縁部３０と、備える。第１側面部２２Ｓは、絶縁部３０に接合されると共に、絶縁部３０との接合強度を高めるためのアルマイト処理がなされた第１外周面２１ａ，第２外周面２１ｂおよび第３外周面２１ｃを含む。第２側面部２１Ｓは、絶縁部３０に接合されると共に、絶縁部３０との接合強度を高めるためのアルマイト処理がなされた第１内周面２２ａ、第２内周面２２ｂおよび第３内周面２２ｃを含む。【選択図】図１
