WIRING CIRCUIT BOARD AND LIGHTING FIXTURE FOR VEHICLE USING THE SAME

PROBLEM TO BE SOLVED: To provide a wiring circuit board excellent in reliability in which a wiring layer does not break even when a wiring width of a board folding portion is narrow.SOLUTION: The wiring circuit board is realized by folding a board 2 along a folding groove as a folding line 6. In this wiring circuit board 1, as to a folding part wiring circuit pattern 4C of a wiring layer 4 positioned on the folding line 6 of the folding groove formed on one surface of the board 2, its both side edges 4Cand 4Cin its wiring width direction obliquely cross the folding line. The folding into an L shape is performed by twisting a board 2B as a folding part relative to a board 2A as a folding counterpart so that sets of both side edges 2Aand 2Bof the both boards do not overlap each other. And thereby, the folding part wiring circuit pattern 4C is lifted from the board 2.
