PROBLEM TO BE SOLVED: To provide a printed circuit board capable of certainly preventing the damage of a conductor pattern caused by a terminal. SOLUTION: A printed circuit board 1a includes a substrate 2, a conductor pattern 6, a through-hole 4, and a non-conductor portion 5. A lead line 22b of a resistor 22 mounted on a printed circuit board 1a is inserted in the through-hole 4. The lead line 22b is bent so that the line protrudes toward the surface 2a of the substrate 2 and the line comes near the surface 2a of the substrate 2. The resistor 22 is attached to the printed circuit board 1a. The non-conductor portion 5 is formed substantially into the shape of a fan which expands with the through-hole 4 at the center as it is closer to the leading end of the lead line 22b. The bent lead line 22b is arranged in the non-conductor portion 5. The non-conductor portion 5 prevents the lead line 22b from coming into contact with the conductor pattern 6 and damaging the conductor pattern 6. COPYRIGHT: (C)2009,JPO&INPIT
