PURPOSE:To obtain the titled sheet inexpensively, by coating a synthetic resin- based sheet with an electroconductive paint containing fine electroconductive metal oxide powder, drying the paint, pressing the fine powder on the surface into the inside of the paint film by hot pressing and smoothing the paint film. CONSTITUTION:An electroconductive paint is prepared by dispersing fine electroconductive powder of SnO2, TiO2 or the like 110 in a synthetic resin. This paint is applied to a synthetic sheet-based sheet 1 of polyvinyl chloride, ABS resin or the like and dried to form a paint film 111. The obtained dry paint film 111 is hot-pressed in the direction of its thickness to press the powder 110 present on the surface of the film into the inside of the film 111 and, at the same time, to soften and roll the film 111 on the surface into a smooth paint film 11. In this way, the purpose antistatic synthetic resin sheet is obtained. This sheet can be suitably used for covering electric devices and appliances because the fine electroconductive powder does not fall of even when the sheet is rubbed.
