ABSTRACT:
The printed wiring board includes a substrate, an electrically conductive pattern formed on the substrate, and an electrical insulator covering the substrate and the electrically conductive pattern therewith, wherein a region of the electrically conductive pattern exposed through an opening formed throughout the electrical insulator is used as the pad, and a region except the pad is used as a circuit wire. The opening has opposite ends extending in a first direction beyond the electrically conductive pattern such that opposite ends of the pad in the first direction are defined by the electrically conductive pattern, and further has opposite ends extending in a second direction perpendicular to the first direction to intersect with the electrically conductive pattern such that the pad is defined in shape in the second direction by the opposite ends of the opening extending in the second direction. The pad is smaller in length in the first direction than the circuit wire.
