PROBLEM TO BE SOLVED: To provide a method of manufacturing a polyglycolic acid resin foam sheet capable of producing the polyglycolic acid resin foam sheet with good foamed state, and the polyglycolic acid resin foam sheet with good foamed state.SOLUTION: A method of manufacturing a polyglycolic acid resin foam sheet includes production of the polyglycolic acid resin foam sheet by carrying out extrusion foaming of a resin composition containing a polyglycolic acid resin and a chain extender having an epoxy group and having epoxy equivalent of 100 g/eq or more and 500 g/eq or less. The resin composition contains 0.05 pt.mass or more and 1 pt.mass or less of the chain extender based on 100 pts.mass of the polyglycolic acid resin. |
