PURPOSE: To provide the information processor capable of improving energy efficiency by effectively utilizing excess heat generated by the information processor.

CONSTITUTION: Insecticidal effect inside the information processor and at its peripheral space is generated by evaporating an evaporative liquid insecticide mounted at an insecticide cartridge fixing housing 4 installed on this side from the side face of a main body 1 of the information processor by using heat generated from a radiating member 5 fitted to heat generating parts 6 inside the main body 1. Thus, energy can be saved by utilizing the heat generated from the information processor as a heat source for an insecticidal device.
