PROBLEM TO BE SOLVED: To provide a cushioning material for electronic equipment, which can easily be deformed, has an excellent cushioning property to strong shock in a short time, such as dropping, and can also cope with fine clearance.SOLUTION: A cushioning material for electronic equipment, comprising a polyolefin-based resin foam having an average foam diameter of 0.02-0.20 mm and an apparent density of 30-100 kg/m, is characterized in that the polyolefin-based resin foam has a foam-breaking rate of 1-30% and a repulsive elastic modulus of ≤40% at 0% compression and after 10 seconds from 80% compression release. |
