PROBLEM TO BE SOLVED: To provide a compact, lightweight and high-quality heat storage device which prevents corrosion of a heat exchanger, and to provide a comfortable and energy-saving air conditioner using the same.SOLUTION: A heat storage device 20A includes a heat storage solution layer 11 consisting of a heat storage solution comprising water, and a heat storage heat exchanger 22 submerged in the heat storage solution layer 11. In the heat storage solution layer 11, a slightly-soluble basic material 14 such as magnesium oxide is submerged. The water quality PH of the slightly-soluble basic material 14 of magnesium base increases up to 10.5 at most, and captures acidic ion which induces corrosion for neutralization so as to keep humoral PH neutral or alkalescent for a long time. Consequently, corrosion of the heat storage heat exchanger 22 is prevented to keep corrosion resistance for a log time.
