However, the shape of the flow path forming concave groove 311 is not particularly limited, and any shape may be used as long as it is formed in the immersion portion 310 to form a part of the refrigerant flow path PR.

As described above, the second evaporator forming plate 300 having the immersion part 310 submerged in water contained in the drip tray TR is connected to the first evaporator forming plate 200 to form a refrigerant flow path PR through which refrigerant flows. Since the evaporator 100 for ice-making is made, it is possible to manufacture the evaporator 100 for ice-making more easily than the conventional ice-making evaporator for making and connecting a finger member (not shown) separately. In addition, the manufacturing cost of the evaporator 100 for ice-making may be reduced, and a defect generation rate may be small when manufacturing the evaporator 100 for ice-making.
