<p>The peel off between an ice making plate and an insulating layer or between the insulating layer and heating means is prevented so that an ice making operation can be performed efficiently. Also, a metal plate is insulated from the heating means reliably. An evaporation pipe 14 and electric heaters H1 to HN are provided in an ice making member 11. A coolant is circulatingly supplied through the evaporation pipe 14 so as to cool the ice making member 11 and ice making water is supplied to the ice making member 11 so as to form an ice block M during the ice making operation. During the deicing operation, heat is generated in the heaters H1 to HN by applying current so that the ice block M is removed from the ice making member 11 by melting. The ice making member 11, in a state that an insulating layer 12b lies between a metal plate 12a to which the evaporation pipe 14 is fixed and the heaters H1 to HN, is formed by bonding the metal plate 12a with the insulating layer 12b, and the insulating layer 12b with each of the heaters H1 to HN by thermocompression. Also, in addition to thermocompression bonding, the external outline of the heating means (H1 to HN) may be located inside the insulating layer 12b.</p> |
