RESIN COMPOSITION, SHEET, AND POROUS FILM

Disclosed is a resin composition containing a filler, a high molecular weight polyolefin, and a polyolefin wax having a weight average molecular weight of 700 to 6,000, wherein the resin composition satisfies the following formula (1), assuming that the weight of the ultrahigh molecular weight polyolefin contained in the resin composition is W1, the weight of the polyolefin wax having a weight average molecular weight of 700 to 6,000 is W2, and the intrinsic viscosity of the ultrahigh molecular weight polyolefin is [·]: · × 4.3 - 21 < W ¢ 2 / W ¢ 1 + W ¢ 2 × 100 < · × 4.3 - 8
