PURPOSE:To improve solderability by forming the pattern shape of one terminal which becomes a bottom side at the time of soldering substantially in a semi-circular shape, and forming the pattern shape of other terminal rising by crossing substantially in a triangular shape of flared state bent at two opposite sides toward its inside, thereby obtaining a preferable solder fillet shape at the time of soldering the pattern of a flexible wiring board (FPC) to that of a printed wiring board. CONSTITUTION:A terminal 110 connected with a conductor pattern 201 formed at the terminal 200 of an FPC 20 is formed at one ends of the circuit patterns 11,... of a printed wiring board 10. The copper foil of the end of the pattern 11... is exposed with the terminal 110 to form a substantially semicircular lands 111.... On the other hand, the terminal 200 is so formed at one end of the FPC20 as to expose the conductive foil. The shape of the pattern 201 of the terminal 200 is formed substantially in an isosceles triangular shape that its base side is wide and its opposite two sides are bent to be reduced toward its inside in a direction of the end to be narrow.
