Patent ID: 8366457

Claim:
A wiring structure, comprising: a board assembly in which a plurality of circuit boards each including a metal foil wire on an insulating board are stacked, and a pin terminal insertion hole is formed by overlapping through-holes formed in the plurality of circuit boards with each other in a board thickness direction; and a pin terminal inserted into the pin terminal insertion hole of the board assembly, wherein, in the pin terminal insertion hole, a terminal connection portion electrically connected to the metal foil wire of the circuit board and fitted onto the pin terminal inserted into the pin terminal insertion hole so as to hold the pin terminal is provided in the through-hole of at least one of the plurality of circuit boards, which forms a part of the pin terminal insertion hole, and at least one insulating sleeve blocking contact of the pin terminal inserted into the pin terminal insertion hole with the remaining circuit boards is fitted into the through-holes of the remaining circuit boards, which form the remaining part of the pin terminal insertion hole.
