PROBLEM TO BE SOLVED: To supress distotion and defect caused by joining when joinning an ice making plate and an evaporator by friction agitation joining. SOLUTION: This ice making apparatus 11 is provided with an ice making part 14 supplied with ice making water to make ice of required shape, and the evaporator 30 disposed at the ice making part 14 to cool the ice making part 14. The evaporator 30 comprises a plurality of body parts 34 in which passages of a refrigerant coming from a refrigerating system are partitioned, and ribs 36 provided in an outward extending manner at the plurality of body parts 34 respectively to abut in close contact with the ice making plate 16 when disposing the body parts 34 at the ice making plate 16. The ice making plate 16 and the ribs 36 are joined by friction agitation joining. COPYRIGHT: (C)2005,JPO&NCIPI
