Abstract: A thermoplastic fiber sheet includes at least cellulosic fibers and thermoplastic resin fibers having a softening temperature of 100 to 140° C. A weight ratio of the cellulosic fibers to the thermoplastic resin fibers (the cellulosic fibers: the thermoplastic resin fibers) is 4:6 to 2:8, and porosity is 20 to 70%.
