Provided are a latent heat storage material having a melting point within a prescribed temperature range; a latent heat. The latent heat storage material includes a compound (A) represented by a formula (A), an inorganic salt (B) represented by a formula (B) and composed of a cation of an alkali metal and an anion of the same element as the anion of the quaternary alkyl salt, and water. The compound (A) is a material that forms a clathrate hydrate together with the water, the composition ratio of the compound (A) and water is a composition ratio that gives a congruent melting point of the clathrate hydrate, and the molar ratio of the inorganic salt (B) to the compound (A) is 0.1 or more and 10 or less.

An object to be cooled is quickly brought to a suitable temperature. An object to be cooled is quickly brought to a suitable temperature. A thermal energy storage packaccording to the present invention is a thermal energy storage pack that performs temperature management of food and/or beverage, and includes a first deep-drawn container filled with a first thermal energy storage material that exhibits phase change at a predetermined temperature, a second deep-drawn container that is overlaid by the first accommodation portion and that is filled with a second thermal energy storage material that maintains a liquid phase state at the phase change temperature of the first thermal energy storage material, and a cover material that closes off the first deep-drawn container. The second deep-drawn container comes into contact with a wine bottle.
