A casing ( 10 ) is formed by insert molding using an inner portion ( 30 ) holding busbars ( 20 ) as an insert. The inner portion 30 includes an interlocking portion ( 33 ) to be hooked in a mold for molding the casing ( 10 ), and is so positioned and supported in the mold by the presence of the interlocking portion ( 33 ) as to project from the inner wall surface of the mold. The interlocking portion ( 33 ) is formed to project toward the inside of the casing ( 10 ) from the inner surface of the casing ( 10 ). The casing ( 10 ) is formed by covering the inner portion ( 30 ) excluding the interlocking portion ( 33 ) by a resin portion ( 13 ).
