PROBLEM TO BE SOLVED: To provide a method for evaluating the degree of deterioration of a resin composition due to water absorption, capable of simply evaluating the degree of deterioration of a resin composition due to water absorption, and a method for evaluating water resistance of a resin composition using the same. SOLUTION: The method for evaluating water resistance of a resin composition includes: a preparation step for preparing a test sample of the resin composition containing an inorganic filler and a resin; a thermal analysis step for performing differential scanning calorimetry of the test sample to obtain a DSC curve; and a heat of fusion calculation step for calculating a heat of fusion from a heat of fusion peak in which 0°C is contained in the DSC curve from the start of fusion to the end of fusion.
