Abstract: A problem to be solved by the invention is providing a laminate sheet which is made of a polyvinyl acetal resin and a methacrylic resin and has excellent transparency, impact resistance, surface hardness, weatherability, moldability, surface smoothness, and the like, and providing a surface protective sheet having excellent adhesion properties with respect to various types of resins and substrates. The problem can be solved by a laminate sheet including at least one polyvinyl acetal resin layer and at least one methacrylic resin layer which is in close contact with the polyvinyl acetal resin layer, the number of carbon atoms of an acetal moiety per 100 carbon atoms which constitute a main chain of the polyvinyl acetal resin being in a range from 30 to 70 and an average degree of polymerization of the polyvinyl acetal resin being in a range from 500 to 2000.
