A thermal storage agent used, for example, for air-conditioning systems of buildings, exhibiting excellent thermal storage, thermal conduction and safety, and a manufacturing method thereof. The thermal storage agent contains particulate oil gel bodies prepared by letting an oil absorbent resin absorb, and thus swell with, a thermal storage oil-soluble substance, wherein the oily gel bodies have a unitary volume of not less than 0.01 cm.sup.3 and are in contact with one another. A manufacturing method in accordance with the present invention can produce the thermal storage agent by letting an oil absorbent resin that is prepared by suspension polymerization in a solution containing the oil-soluble substance absorb, and thus swell with, the oil-soluble substance.

[ What is claimed is:] [1.] A thermal storage agent, comprising an oily gel body containing:4-20 percent by weight of an oil absorbent resin which is prepared by polymerizing a monomer component containing at least one aliphatic hydrocarbon group having a carbon number of from 3 to 30 and also containing not less than 50 weight percent of at least one unsaturated compound selected from the group consisting of alkyl(meth)acrylate, alkylaryl(meth)acrylate, alkyl(meth)acrylamide, alkylaryl(meth)acrylamide, aliphatic vinyl esters, alkyl vinyl ethers, and alkylstyrenes; and96-80 percent by weight of a thermal storage oil-soluble substance,wherein said oily gel body has a unitary volume of not less than 0.01 cm.sup.3.
