Claim:
1. A formed product containing a 4-methyl-1-pentene polymer, comprising 0.01 to 10 parts by mass of a 4-methyl-1-pentene polymer (B-1) per 100 parts by mass of a propylene resin composition (X), wherein: the 4-methyl-1-pentene polymer (B-1) has (B1) an intrinsic viscosity [η] of 0.01 or more but less than 0.50 dl/g measured at 135° C. in a decalin solvent, and (B4) a melting point (Tm) in the range of 120° C. to 245° C. as measured with a differential scanning calorimeter, and the propylene resin composition (X) contains 60 to 100 parts by weight of a propylene polymer (A-1) and 0 to 40 parts by weight of a propylene polymer (A-2) (the total of the (A-1) component and the (A-2) component is 100 parts by weight), the propylene polymer (A-1) has (A-1-1) a Shore A hardness in the range of 20 to 94, (A-1-2) a constitutional unit derived from propylene in the range of 51% to 100% by mole, and (A-1-3) a melting point less than 100° C. or no melting point as measured by DSC, and the propylene polymer (A-2) has (A-2-1) a melting point of 100° C. or more but less than 175° C. as measured by DSC.
