PROBLEM TO BE SOLVED: To provide a fiber reinforced material which can be suitably used as a biocompatible material and has high tear strength, and a method for producing the same. A fiber reinforced material in which a fiber base material and a resin composition containing a polymer are integrated, and the polymer is a monomer having an ethylenically unsaturated group and two or more hydroxyl groups. A fiber-reinforced material having a structural unit derived from (A) and at least one structural unit derived from a monomer (B) having an ethylenically unsaturated group and a lactam ring.
