Zusammenfassung:	It is an object of the present invention to provide a modified propylene resin containing very small amounts of low-crystalline and low-molecular-weight components. The present invention relates to a modified propylene resin characterized by satisfying the following requirements (1) to (4). (1) The melting point (Tm) measured with a differential scanning calorimeter (DSC) is 140° C. or higher. (2) The amount of grafts of ethylenic unsaturated bond-containing monomer after hot xylene washing is 0.1 to 5 percent by weight. (3) The amount of components soluble in o-dichlorobenzene at 70° C. is 1.5 percent by weight or less. (4) The intrinsic viscosity [eta] is 0.1 to 4 dl/g.
