PROBLEM TO BE SOLVED: To provide a rigid foam resin in which a groove is not found between portions with different physical properties and a boundary phase of each portion is fixed, and a method of molding the same and a mold for molding. SOLUTION: In molding a shock absorbing material 7, an insert molded article 5 molded by another mold in advance is arranged in a mold 1, and is temporarily fastened by thrusting into a locking part 4. After supplying a raw liquid R for foam molding to a residual space in a lower mold 3, the mold is closed and the raw liquid R is foamed by heating or the like, and a portion 6 with different hardness from hardness of the insert molded article 5 is molded. The shock absorbing material 7 has two portions with different shock absorbing characteristics including a portion derived from the insert molded article 5 and a portion 6 foam molded in the mold 1.
