A connecting structure is for a printed wiring board to be electrically connected to a FPC. The FPC includes a substrate and electro-conductive portions. The printed wiring board includes an insertion opening provided on an edge surface thereof, and line connecting terminals formed on an inner wall face of the insertion opening. A dual in-line contact member including first contact members is fixed to the top end portion of the FPC. Each first contact member includes a main body, and a first arm and a second arm extending from the main body generally in parallel to each other. Furthermore, the first arm and the second arm are bent at bent portions so as to form curves protruding away from each other. With the present embodiment, at least one of the first arm and the second arm press the corresponding line connecting terminal provided within the insertion opening at the bent portion thereof by inserting the FPC to the insertion opening of the printed wiring board. Thus, the FPC is connected to the edge surface of the printed wiring board. This improves the freedom from the perspective of design of the wiring pattern as well as allowing mounting of circuit components with high circuit density.
