[Problems to be solved by the invention]
However, the external dimensions formed by machining in the connecting component 111 and the positional relationship between the conductive portions 115 formed by the printing technique are completely different from each other, so that the dimensional tolerances S1 and S2 of the positional relationship between them can be reduced.
