PROBLEM TO BE SOLVED: To provide a thin and flexible resin foam sheet having a low apparent density with excellent stability at the time of being wound up (winding-up stability).SOLUTION: A resin foam sheet has a 0.02-0.30 g/cmapparent density, a 0.5-3.0 MPa tensile strength, a 0.20-0.70 mm thickness, a 5 m or more length, a 300 mm or more width, and an opening on both sides. The value obtained from formula (1) is 30% or less. Formula (1): (thickness tolerance)/(thickness center value) ×100. |
