  By the way, in order to energize the electric device mounted on the vehicle, the wiring constituting the electric circuit must be connected to the harness terminal extending from the electric device or the harness connected to the driving power source of the electric device. Therefore, it is required to make the connection structure inexpensive without complicating it. However, Patent Document 1 does not mention this at all.

  On the other hand, in patent document 2, after joining the sheet-like object in which the electric circuit was formed to the door inner panel main body, the pin which protrudes from a connector is inserted in the hole formed on the wiring of an electric circuit, and the said connector is door inner panel. In this state, the door inner panel body is immersed in a copper electroless plating bath to deposit copper on the electrical circuit, and the wiring and pins of the electrical circuit are connected by the deposited electroless plating layer. However, the manufacturing process becomes complicated.

  Further, in Patent Document 2, a protrusion is greatly protruded from the door inner panel body to form an electric circuit wiring, and a case having a surface contact on the inner surface is fitted to the protrusion to Although it is also disclosed that the contact is connected to the wiring of the electric circuit, if the protruding part is greatly protruded on the door inner panel body, the electric circuit formed by bending and forming a sheet-like object at the time of vacuum forming is disconnected. There is a risk. In addition, a sheet-like material for forming an electric circuit is necessary and expensive, and the manufacturing process becomes complicated.
