Abstract: A molded product formed of a plurality of portions containing 4-methyl-1-pentene polymers in contact with each other and to provide a method for producing the molded product. A molded product according to the present invention includes a composition containing a particular 4-methyl-1-pentene (co)polymer (A) having a melting point (Tm) measured by DSC of within the range of 200 to 250° C. and a particular 4-methyl-1-pentene copolymer (B) having no observed melting point (Tm) or having a melting point (Tm) of within the range of 100 to 199° C., the melting point (Tm) being measured by DSC, wherein a content of the (co)polymer (A) is 60 to 95 parts by mass of based on a total of 100 parts by mass of the (co)polymer (A) and the copolymer (B), and a portion (2) that contains the 4-methyl-1-pentene (co)polymer (A) and is formed in contact with the portion (1).
