The present invention provides a molded product exhibiting excellent various properties by improving compatibility of an ethylene/&#x3b1;-olefin/non-conjugated polyene copolymer with a polyolefin resin and a rubber composition for forming the molded product. The present invention further provides a molded product which comprises a rubber composition, is inhibited from fogging and tackiness and is excellent in mechanical strength and heat aging resistance. The rubber composition of the invention comprises an ethylene/&#x3b1;-olefin/non-conjugated polyene copolymer (A), and a polyolefin resin (B) having Mn of not less than 10,000 and/or an ethylene/&#x3b1;-olefin copolymer (C) having Mn of 2500 to 5000, and satisfies the following requirements: (1) a maximum value and a minimum value of an ethylene distribution parameter P of the component (A) have a relationship of Pmax/Pmin&#x2266;1.4, and (2) the B value of the component (C) ([EX]/(2[E]&#xd7;[X])) ([E] and [X] are molar fractions of ethylene and the &#x3b1;-olefin of 3 to 20 carbon atoms, respectively, and [EX] is a fraction of dyad sequence of ethylene/&#x3b1;-olefin of 3 to 20 carbon atoms) is not more than 1.05.
