To provide a polyphenylene ether laminated sheet which is almost free from warpage and best suited for its use applications by setting the ratio of the resin composition amount of one of the surface layers to a total resin composition amount to a specific value.

A resin composition of heat-curable polyphenylene ether resin is a composition containing a polyphenylene ether such as poly(2,6-dimethyl 1,4-phenylene ether) obtained by monopolymerizing 2,6-dimethylphenol, as a component. In addition, in order to upgrade the physical properties of a base which is laminate-molded, a resin composition of polyphenylene ether resin, epoxy resin or the like is melted or dissolved in a solvent and the base material of various kinds of glass cloth such as roving cloth, and an asbestos cloth, a metallic fiber cloth and other kinds of fiber cloth such as synthetic or natural inorganic are impregnated with the molten or dissolved resin composition. The ratio of the resin composition amount of one of the surface layers to a total resin composition amount is 45-55 wt.%. Thus the obtained laminated sheep is almost free from warpage and is best suited for its use applications as a polyphenylene ether laminated sheet.
