摘要： The present invention provides a heat dissipating member having excellent heat dissipation properties and suitable for use in an oil environment. The present invention is a heat dissipating member including: a porous base material containing a fluorine resin and a thermally-conductive filler; and an oil contained in pores of the porous base material. The fluorine resin contains polytetrafluoroethylene. The heat dissipating member can be produced, for example, by a method including the steps of: (1) stacking and rolling together a plurality of sheet-shaped formed bodies each containing a polytetrafluoroethylene-containing fluorine resin, a thermally-conductive filler, and a molding aid, so as to obtain a rolled laminated sheet; (2) removing the molding aid from the obtained rolled laminated sheet to obtain a porous base material; and (3) impregnating the obtained porous base material with an oil.
