description The present invention provides a powdered polycarbodiimide compound which can improve the hydrolytic resistance of an ester resin, hardly causes an increase in viscosity when added to and mixed with the ester resin, and has high handling properties, and an ester resin composition comprising the same. The powdered polycarbodiimide compound according to the present invention is represented by the following formula (1), and has a melting point of 50°C or more:wherein R1 and R2 each represent a residue of an organic compound (excluding ethanol) having one functional group reactive with an isocyanate group, wherein the functional group is removed from the organic compound; R3 represents a divalent residue of a diisocyanate compound from which two isocyanate groups are removed; the diisocyanate compound has a hydrocarbon group which directly bonds to the two isocyanate groups; R4 represents a divalent residue of a diol compound from which two hydroxyl groups are removed; X1 and X2 each represent a bond formed by a reaction of the functional group with the isocyanate group; m and n each represent a number of 1 to 20; and p represents a number of 2 to 20.
