Provided is a fine paper powder-containing resin molded object with a content of a thermoplastic resin being reduced to offer a lighter weight and a superior mechanical strength, and a manufacturing method thereof. The fine paper powder-containing resin molded object (1) is made from a thermoplastic resin containing fine paper powder and is composed of a non-foam layer (2) formed on the surface and a foam layer (3) formed in the inner side. The foam layer (3) has, in the order from the surface side, a first foam layer (3a) containing cells having an average cell diameter ranging from 10 to 100 μm, a second foam layer (3b) containing cells having an average cell diameter from 5 to 50 μm, and a third foam layer (3c) containing cells having an average cell diameter from 20 to 500 μm. The molded object (1) contains an aromatizing ingredient.
