Abstract: Curable polyolefin composition comprising: (A) polyolefin having at least two aliphatic unsaturated bonds per molecule; (B) wax with melting point of 30 to 100° C.; (C) organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; and (D) catalytic amount of hydrosilylation reaction catalyst, wherein content of component (A) is 20 to 80 mass %, content of component (B) is 10 to 75 mass %, and content of component (C) is 1 to 20 mass %, each based on the total mass of components (A) to (D). The composition can be cured to form a cured product capable of storing and releasing thermal energy, and preventing the wax leaking/pumping out during heat cycling.
