| 发明名称 | Ceramic heater | ||
| 摘要 | A ceramic heater is constructed by embedding a heat-generator in a base body made of ceramics. The heat-generator has a recess in a surface thereof, the ceramics being inside the recess. Even if a great thermal stress is developed due to a difference in thermal expansion between the heat-generator and the base body, by the recess inside which the ceramics that forms the base body exists, occurrence of a gap between the heat-generator and the base body, as well as appearance of cracks in the base body, can be prevented even in the direction of the length of the heat-generator in which the thermal stress is applied heavily. | ||

| 主权项 | 1. A ceramic heater, comprising: a heat-generator having at least one recess; and a base body made of ceramics, the base body enclosing the heat-generator, the heat-generator including two opposed portions arranged in juxtaposition and a connection portion for connecting the two opposed portions together in arcuate form, the at least one recess of the heat-generator being located in at least one of the connection portion and the two opposed portions of the heat-generator and being filled with the base body, and a dimension of the at least one recess in a longitudinal direction of the heat generator being greater than or equal to 1/10 and less than or equal to ½ of a length of the at least one of the connection portion and the two opposed portions. | ||
