PURPOSE: To provide a thermal storage unit comprising an organic thermal storage medium supported on a low crystalline polyolefin substrate and a thermal storage element, having an oil-resistant resin film on the surface thereof, capable of reducing the exudation of the thermal storage medium and having a small dimensional change without causing the deformation and mutual sticking. CONSTITUTION: This thermal storage unit 1 comprises a substrate composed of preferably 10-30wt.% low crystalline polyolefin having <40% crystallinlty and preferably 70-90wt.% organic thermal storage medium, supported on the substrate and capable of reversibly displaying the phase transition between the solid and the liquid phases as constituent materials. Furthermore, the objective element has an oil-resistant resin film (e.g. PE, PP, nylon or polyethylene terephthalate) 2 on the surface of the thermal storage unit 1. |
