Abstract
The present invention relates to a method for producing a resin composition foam comprising dissolving a supercritical fluid in a resin composition containing polytetrafluoroethylene and another resin other than polytetrafluoroethylene at a temperature equal to or higher than a glass transition point of the other resin, then foaming the resin composition by removing the supercritical fluid at a temperature lower than a temperature obtained by adding 15° C. to a thermal deformation starting temperature of the other resin, and subsequently cooling. In addition, the present invention relates to a resin composition foam, wherein the resin composition foam has a pore size of less than 50 μm, and the resin composition foam is any one of an open cell, a closed cell and a monolith type.
