PROBLEM TO BE SOLVED: To provide a resin composition for polyolefin resin foam capable of forming a foam having uniform and fine cells while maintaining sufficient foaming ratio or flexibility even when a discharge speed is high and a polyolefin resin foam having uniform and fine cells while maintaining sufficient foaming ratio or flexibility.;SOLUTION: The resin composition for polyolefin resin foam contains (A) polyolefin having melt flow rate (MFR) of 0.2 to 0.7 g/10 min. at a temperature of 230°C and melting tensile force during breaking measured at the temperature of 190°C of 30 cN or more and (B) polyolefin having melt flow rate (MFR) of 1.5 to 10 g/10 min. at a temperature of 230°C and melting tensile force during breaking measured at the temperature of 190°C of 10 cN or more with the content of the polyolefin (B) of 15 to 75 pts.wt. based on 100 pts.wt. of the polyolefin (A).;SELECTED DRAWING: None;COPYRIGHT: (C)2016,JPO&INPIT
