PROBLEM TO BE SOLVED: To provide a printed wiring board which can be manufactured with at a few processes and is excellent in productivity, and provide a modular component using the printed wiring board and a method for manufacturing the printed wiring board. SOLUTION: In the printed wiring board 12, protruding parts 11 composed of a metal material are formed on a prescribed part of a wiring pattern formed on a substrate 10, and the dispersion of the height of the protruding parts 11 is made at most±5μm. Gaps between an external electrode of a mounted electronic component and the protruding parts 11 can be made small, so that the reliability of connection is improved. COPYRIGHT: (C)2004,JPO&NCIPI
