Abstract
A composite sintered body includes a base material (i.e., a main body) using ceramics as a main material and an electrode disposed inside the main body or on a surface thereof. The electrode contains WC and TiN. It is thereby possible to reduce the difference in thermal expansion coefficient between the electrode and the main body while suppressing an increase in the resistivity of the electrode. As a result, it is possible to suppress any damage such as a crack, a breakage, or the like of the main body, which is caused by the difference in the thermal expansion coefficient.
