A method for producing compression-melt molded product using polylactic acid powder is described. The method comprises the steps of: 1) heat-melting polylactic acid having a weight-average molecular weight of 3,000-40,000 at 140-220&#xb0; C., 2) allowing the melted polylactic acid to cool down to solidify at an ordinary or a lower temperature, 3) pulverizing the solidified polylactic acid at an ordinary temperature into powder, and 4) compressing the powder or a mixture powder prepared by addition of another ingredient, e.g., a biologically active compound, to the carrier powder in a mold at an ordinary temperature to cause the polylactic acid to melt into a molded product of a predetermined shape.
