A phosphorus-containing compound represented by formula (I) and a preparation method thereof are provided. An addition reaction is performed for an organic cyclic phosphorus compound with an aryl aldehyde compound, and then a condensation reaction is performed with an aryl compound having active hydrogen in the use of an organic acid as a catalyst to obtain the proposed phosphorus-containing compound. This phosphorus-containing compound can be used as a hardener for resin, and improves flame retardant properties and thermal resistance for a flame retardant epoxy resin composition, thereby suitably applied to resin compositions used for manufacturing printed circuit boards and laminated circuit boards in electronic or electric products.
