Abstract
There is provided a polyolefin resin foam sheet having a plurality of cells which is formed by foaming a polyolefin resin composition, wherein the polyolefin resin composition contains a polyolefin resin (A) having relatively high density and a polyolefin resin (B) having relatively low density, and the weighted average resin density of the polyolefin resin (A) and the polyolefin resin (B) is 0.900 g/cmor less; and wherein a ratio [TD strength at break/MD maximum cell size] and a ratio [MD strength at break/TD maximum cell size] are both 45 kPa/μm or more.
