PROBLEM TO BE SOLVED: To provide a method enabling simple low cost manufacturing of an engine housing latent heat accumulating material. SOLUTION: Particulate anhydride is injected in a lower jacket 112e formed inside an engine block 110 (anhydride injection process). Then, the anhydride is hydrated in the lower jacket 112e to form latent heat accumulating material LM (hydration process). Consequently, the engine 100 is formed which has a structure housing latent heat accumulating material LM having characteristics accumulating latent heat in a supercooling state in the engine block 110.
