Molded body, downhole tool member, and downhole tool

Abstract

Provided is a molded body that has an improved thickness reduction rate after a thickness reduction of 5 mm or greater from its initial thickness, while maintaining tensile strength. The molded body of the present invention includes a glycolic acid polymer, a cyclic ester, a basic metal oxide and a carboxylic anhydride. A content of the cyclic ester is 21 parts by mass or less when a total mass of the glycolic acid polymer, the cyclic ester, the basic metal oxide, and the carboxylic anhydride is 100 parts by mass. The shortest interparticle distance of the basic metal oxide is 9.1 μm or less.
