のである。The present invention involves supplying thermoplastic synthetic resin particles ranging from small particle sizes to large particle sizes onto the surface of a base material layer from a feeder having a doctor knife to form thermoplastic synthetic resin particles on the base material layer. is applied and then heated and pressurized to fuse the thermoplastic synthetic resin grain layer to the base material layer, and at the same time fuse and crush each thermoplastic synthetic resin grain to each other. In the manufacturing method, thermoplastic synthetic resin particles with an angle of repose of 60° or less are used, and doctor knives with a wedge-like shape and a cutting edge thickness of 5 mm or less are used (manufacturing of interior materials for external use). The present invention provides a method.
