PROBLEM TO BE SOLVED: To provide a small wiring board and a multiple wiring board capable of easily distinguishing a forming place of a defective wiring board from the wiring board and the multiple wiring board, and having a mark capable of aligning when mounting an electronic component. SOLUTION: The wiring board has a mounting part 1a for mounting an electronic component on at least one main surface of an insulating board 1, and a wiring conductor 2 electrically connected with the electronic component is formed on the surface or an inside of the wiring board. The mark 3 is formed in the insulating board 1 at a place not so as to overlap with the wiring conductor 2 in plane vision. COPYRIGHT: (C)2005,JPO&NCIPI
