To provide a heat storage type heat supply device capable of efficiently recovering heat in a short time.

This heat storage type heat supply device 1 comprises a heat storage body 6 for storing heat on the basis of a state variation between solid and liquid, and a storage container 2 exchanging heat by directly kept into contact with the heat storage body 6 having specific gravity smaller than that of the heat storage body 6, and receiving a heat exchange medium 5 not mixed with the heat storage body 6. A plurality of supply portions 3, 4 each supplying the heat exchange medium 5 to the heat storage body 6 are formed at a lower portion in the storage container 2. Further a flow rate adjusting means is disposed to adjust a supply flow rate of the heat exchange medium 5 from at least one of the plurality of supply portions 3, 4 into the heat storage body 6.
