A method of producing a multilayer sheet, the method comprising:
- bringing, in a molten state of 160° C. or higher, a substrate layer (A) that comprises 40 to 99.9% by mass of a polyphenylene ether (a1), 0 to 59.9% by mass of a polystyrene (a2), and an amino group-containing polymer (a3) into contact with an adhesive layer (B) that comprises an acid-modified polyolefin.
A multilayer sheet comprising,
- a substrate layer (A) that comprises 40 to 99.9% by mass of a polyphenylene ether (a1), 0 to 59.9% by mass of a polystyrene (a2), and an amino group-containing polymer (a3);
- and
- an adhesive layer (B) that comprises an acid-modified polyolefin,
- wherein the substrate layer (A) has a storage modulus at 160° C. of 500 MPA or more.
