Claims

[Claims for Utility Model Registration] A plurality of flexible printed circuit boards whose surfaces on which printed circuit patterns are formed are covered with a cover film, in which a portion of each flexible printed circuit board is not covered by the cover film and the circuit pattern connection portion is exposed. A cover film opening is provided, and a through hole is bored approximately at the center of the printed circuit board in the cover film opening, so that the cover film openings are opposed to each other, and the printed circuit boards are connected to each other through the through hole. In a connection structure for a flexible printed circuit board in which the circuit pattern connection parts are brought into contact with each other by tightening the screws with screws, a through-hole for screw insertion is provided at the center between the screws and the flexible printed circuit board; A connection structure for a flexible printed circuit board, characterized in that a pressing member that does not protrude from the area of a cover film opening is provided.
