Abstract
To present printed wiring boards and other electronic components having excellent cockroach repelling performance even after solder reflow or solder flow. A conductive layer having a mounting land is provided on a insulating layer as a substrate, a solder resist is applied to cover the conductive layer excluding the mounting land, and an electronic component material containing a cockroach repellent is applied on the solder resist. This electronic component material is a paste containing a resin curable by crosslinking, a cockroach repellent, and a filler such as silica or talc, and by crosslinking and curing the resin by chemical reaction, a dried cockroach repelling layer is exposed and formed on the surface of the printed wiring board.
