To provide a check pattern whereby whether via-hole openings are made correctly or not can be examined without needing high precision positioning of the via-holes, a check pattern of the invention comprises: a check wiring (3) configured on a semiconductor substrate (2), an insulation film (4) formed on the semiconductor substrate (2) to cover the check wiring; and a pair of via-holes (6) each configured at each end of the check wiring (3), said each (6) positioned slightly shifted inversely with each other from a center line in a width direction of the check wiring (3), and a bottom of said each (6) being positioned to traverse both the check wiring (3) and the insulation film (4).
