PROBLEM TO BE SOLVED: To shorten an overhang distance relative to a printed wiring board. SOLUTION: At both ends of a coupon region E2, first and second through holes 14, 15, 31, and 32 are provided. Between the first and second through holes 14, 15, 31, and 32, conductor patterns 24-29 are extended for electrical connection of through holes 14a, 15a, 31a, and 32a. The extension direction of the conductor patterns 24-29 is identical with the side-by-side provision direction of the through holes 14a, 15a, 31a, and 32a. Thus, the test coupon 12 is extended along the edge part of a printed wiring board 11, not proportional to the number of through holes.
