PROBLEM TO BE SOLVED: To provide a curing sheet, to which anti-slip properties are applied, obtained by reducing the easy-to-slip properties being the flaw in a case used as various curing materials of plastic corrugated cardboard, which comprises two-layered constitution wherein a cap sheet having a large number of dents and a flat back sheet both of which are made of a plastic material such as polyethylene or the like are laminated along the surface of the bottom part of the cap sheet or three-layered constitution wherein a flat liner sheet is laminated to the surface formed by joining the apexes of the caps of the cap sheet in addition to the two-layered constitution, to a degree not becoming a problem from a practical aspect. SOLUTION: A curing sheet to which anti-slip effect is applied is obtained by bonding a lace-like sheet, which is produced from an olefinic elastomer like an ethylene/propylene copolymer, to the surface, which is formed by joining the apexes of caps, or liner sheet and back sheet of plastic corrugated cardboard. If it is unnecessary to bond the lace-like sheet to both surfaces of plastic corrugated cardboard, the lace-like sheet may be bonded to either one of both surfaces of the plastic corrugated cardboard.
