Zusammenfassung:	There is provided a polyolefin resin foam sheet formed by foaming a polyolefin resin, wherein the expansion ratio of the foam sheet is 1.5 to 20 cm3/g, the average cell sizes in the MD direction and the TD direction of the foam sheet are 130 µm or less, and the following formulas (1) and (2) are satisfied: TM/D≥6 and TT/D≥5 whereTM denotes the tensile strength at 90°C in the MD direction,TT denotes the tensile strength at 90°C in the TD direction, andD denotes the density (g/cm3) of the foam sheet.
