PROBLEM TO BE SOLVED: To provide a method for producing a biodegradable waterproof fabric which can be biodegraded with organisms and biological substances existing in the natural field to avoid problems on disposal, when buried in soil for the disposal after used. SOLUTION: This method for producing the biodegradable waterproof fabric, characterized by using aliphatic polyester conjugate fibers comprising two or more kinds of aliphatic polyesters, such as polylactate, having a melting point difference of >=10 deg.C therebetween as wefts and warps to produce the woven fabric having a cover factor of >=1,200 and then thermally treating the woven fabric at a temperature between the melting points of two kinds of the aliphatic polyesters by the use of a tenter or the like to fill spaces among the wefts and warps of the woven fabric.
