PROBLEM TO BE SOLVED: To provide a biodegradable wax composition excellent in moisture-proof properties and easy to melt-mold. SOLUTION: The wax composition is mainly composed of a wax, contains a biodegradable polymer substance and a filler, and has moisture-permeability of at most 3 g×mm/m<SP>2</SP>×24 hr at 40°C and 90%RH. Preferably, the content of the wax is 65-95 wt%. The weight-average molecular weight of the biodegradable polymer substance is preferably at least 200,000. COPYRIGHT: (C)2005,JPO&NCIPI
