PROBLEM TO BE SOLVED: To provide a printed wiring board in which a probe pin is prevented from being shifted. SOLUTION: A check land 5 is formed at a part of a conductor pattern on a multilayer substrate and a protrusion 7 for preventing shift of a probe pin is printed around the check land 5. A marking ink layer is employed as the protrusion 7 for preventing shift of a probe pin. Since a wall of the protrusion (ink layer) 7 is provided by silk printing around the check land 5, a probe pin 8 is prevented from shifting to the outside of the check land 5.
