Abstract: Invasion of insects into electronic appliances is prevented, nesting of insects in the electronic appliances is prevented, and these preventing actions are maintained for a long period. Further, troubles of electronic appliances due to invasion of insects are decreased. Insect control measures may be applied in all electronic appliances including small and lightweight types. It includes (a) a housing, and (b) an electronic circuit disposed in the housing. The electronic circuit includes a printed wiring board having an electronic material containing a repellent, and an electronic component mounted on the printed wiring board. The electronic material containing the repellent is paste, solder resist, parts layout, insulating resin, prepreg cured piece, resin film, or polyimide film.
