Abstract
A method for reducing an electromagnetic disturbance wave generated at an electronic apparatus, by covering the electronic apparatus with a housing which is formed by a material having a shield effect against an electromagnetic wave, includes providing a space forming part for radiation of heat or wiring at the housing, so that a longitudinal direction of the space forming part is along a surface electric current distribution in a case where the space forming part is not provided at the housing.
