Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous polyurethane resin composition for a glass fiber sizing agent having excellent glass fiber sizing property, a glass fiber sizing agent using the same, glass fibers for a reinforced resin obtained by treatment with the glass fiber sizing agent, and a glass fiber-reinforced resin having excellent mechanical strength.SOLUTION: The aqueous polyurethane resin composition is produced by dispersing an urethane resin, obtained by reacting an epoxy ester compound and polyisocyanate, in water with the use of an emulsifier. The epoxy ester compound includes a ricinoleic acid epoxy ester compound represented by general formula (1) as an essential component, where in formula, R is each independently H or 1-3C alkyl, and n is a number of 0-3.
