PROBLEM TO BE SOLVED: To provide a laminate having proper rigidity by using a general-purpose resin raw material, excellent in cushioning properties, lightweight properties, moldability or water resistance, low in production cost and utilizable as an excellent packaging container or material. SOLUTION: A laminate 1 is constituted by integrally laminating a mixed resin foam layer 3 with a density of 0.065 g/cm3 or less based on 30-55 wt.% of (1) a polystyrenic resin, 30-50 wt.% of (2) a polyethylenic resin with a density of 0.89-0.93 g/cm3 and 10-30 wt.% of (3) a polyethylenic resin with a density of 0.94-0.97 g/cm3 [the sum total of (1), (2), (3) is 100 wt.%] on at least the single surface of a polystyrenic resin foam layer 2.
