A salt of carboxyethyl phosphinate ester is provided to show excellent flame retardant property, improved heat-stability and moisture absorbing property by esterifying carboxy phosphinic acid and then preparing a salt compound thereof. The salt of carboxyethyl phosphinate ester is represented by the formula(I), where R1 is C1-6 alkyl, C6-12 aryl or alkyl substituted C6-12 aryl, R2 is C1-6 alkyl, C6-12 aryl or alkyl substituted C6-12 aryl, n is an integer from 1 to 3, and M is a metal selected from the group consisting of Al, Zn, Ca, Ba and Mg or an amine-based compound selected from the group consisting of ammonium, melamine and melum. The flame retardant thermoplastic resin composition comprises a thermoplastic resin and 0.1-50 parts by weight of the salt of carboxyethyl phosphinate ester regarding 100 parts by weight of the thermoplastic resin.
