Abstract
A resin-impregnated sheet material is manufactured by passing a sheet material through a vacuum space of a reduced pressure sufficiently different from ambient atmospheric pressure for sufficiently deaerating the sheet material at the vacuum space, and impregnating the thus deaerated sheet material with a resin varnish while utilizing the pressure difference between the atmosphere and the vacuum space, the sufficiently deaerated sheet material being impregnated quickly and reliably with the resin varnish to provide the resin-impregnated sheet material of high quality.
