PROBLEM TO BE SOLVED: To provide an ice plant capable of making the ice of functionally high quality by improving the transparency and making a mineral component inconspicuous even when the ice is put in drinks. SOLUTION: A cooling accelerating member 12 having the heat conductivity higher than that of an ice making case 4 is buried in a bottom face of the ice making case 4 in a state of being kept into contact with a cooling plate 3. The water supplied to the ice making case 4 is frozen from a bottom face toward an upper face as it is cooled by the cooling plate 3. As a temperature of a peripheral part where the cooling accelerating member 12 is buried, of the bottom face of the ice making case 4 is lower than that at the other part of the bottom face of the ice making case 4, the ice grows into the projecting shape having a height of its central part higher than that at a side face of the ice making case 4 when it is observed from a vertical cross-section. As the air is diffused from the upper face of the ice making case 4 to the external, and the mineral component is dispersed to the side face of the ice making case 4, the ice of high transparency can be made.
