PROBLEM TO BE SOLVED: To provide a control device which can enhance the welding quality of weld parts between terminals and bus bars, and can prevent a short circuit between and among a plurality of the terminals.SOLUTION: In a control device, a plurality of terminals 11 protruding from a control part 10 and a plurality of bus bars 21 exposed from wiring members for loading the control part 10 are weld-joined to each other. Bulkheads 30 arranged between the plurality of the terminals 11 have notched grooves 33 in vicinities of weld parts 13 between the terminals 11 and the bus bars 21. Insulation bodies 40 which are covered on the weld parts 13 between the terminals 11 and the bus bars 21, and block a plurality of the notched grooves 33 prevent the intrusion of foreign matters into spaces which are partitioned by the bulkheads 30, and in which the terminals 11 are placed from the notched grooves 33. Since the notched grooves 33 are formed at the bulkheads 30, when the terminals 11 and the bus bars 21 are laser-welded, the generation of fume from the bulkheads 30 caused by the reflection of laser light can be prevented. 【課題】ターミナルとバスバーとの溶接部の溶接品質を高めるとともに、複数のターミナル同士の短絡を防ぐことの可能な制御装置を提供する。【解決手段】制御装置は、制御部１０から突出する複数のターミナル１１と、制御部１０を載置する配線部材から露出した複数のバスバー２１とが溶接接合される。複数のターミナル１１の間に設けられた隔壁３０は、ターミナル１１とバスバー２１との溶接部１３の近傍に切欠溝３３を有する。ターミナル１１とバスバー２１との溶接部１３に被さると共に複数の切欠溝３３を塞ぐ絶縁体４０は、隔壁３０により仕切られたターミナル１１の設置される空間に切欠溝３３から異物が入り込むことを防ぐ。隔壁３０に切欠溝３３を設けたことにより、ターミナル１１とバスバー２１とをレーザ溶接する際、レーザ光の反射により隔壁３０からヒュームが生じることが防がれる。【選択図】図５
