To develop a decorative sheet using a polylactic acid-based resin to reduce environmental impact, the makeup ratio is increased by increasing the biomass ratio of the decorative sheet and providing the same level of performance as a conventional petroleum-based plastic decorative sheet. Providing a sheet. A thermoplastic resin sheet base material 1 is composed of at least a polylactic acid resin and a polyolefin resin, and each has a co-continuous structure having a continuous layer structure, (A) a polylactic acid resin, (B) It consists of a polyolefin resin, (C) modified layered silicate, (A) 30 to 70% by weight, (B) 30 to 70% by weight, and (C) 3 to 10% by weight.
