PROBLEM TO BE SOLVED: To provide a resin composition with low permittivity and dielectric loss tangent, providing a flame-retardant cured product, and a prepreg, a laminated sheet and a multilayer printed circuit board prepared by using it. SOLUTION: The resin composition comprises a cross-liking component with a wt. average molecular wt. of 1,000 or less and having a multifunctional styrene group of formula 1 (wherein R is an optionally substituted hydrocarbon; R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>are each a H atom or a 1-6C hydrocarbon group; R<SP>5</SP>, R<SP>6</SP>, R<SP>7</SP>and R<SP>8</SP>are each a H atom or a 1-20C hydrocarbon group; and n is an integer of 2 or more) and a bromine compound, used for preparation of the prepreg, the laminated sheet and the multilayer printed circuit board.
