In either case, the terminals 13 are attached to the edges of the child circuit board 12, the terminals 13 are fixed to the child circuit board 12 by soldering, and then the terminals 13 are connected to the parent circuit board 11. Reference numeral 14 indicates soldering between the child circuit board 12 and the terminals 13. The child circuit board 12 is, for example, a ceramic board 15.
A circuit pattern 16 is formed using a high-temperature firing type conductive paste, and a solder resist 17 is further printed.
