PROBLEM TO BE SOLVED: To provide a cooling plate which is locally deformed little and can be used as a backing plate having the long life before being replaced. SOLUTION: The backing plate (cooling plate) 1 has a channel 6 for passing a refrigerant therein, which is formed by blocking a groove 5 formed in a main body 2 with a lid 3. The lid 3 has a larger width than the groove 5, and has a salient 4 on at least one surface (on inner side in figure 1). COPYRIGHT: (C)2007,JPO&INPIT
