Stage: PROBLEM TO BE SOLVED: To reduce a difference in a coefficient of thermal expansion between an electrode and a base material while suppressing an increase in resistivity of the electrode.SOLUTION: A composite sintered body 20 includes a base material mainly made of ceramic (that is, a main body portion 21), and an electrode 23 arranged inside or on the surface of the main body portion 21. The electrode 23 includes WC and TiN. As a result, it is possible to reduce a difference in the coefficient of thermal expansion between the electrode 23 and the main body portion 21 while suppressing an increase in the resistivity of the electrode 23. As a result, damage such as cracks in the main body portion 21 due to the difference in the coefficient of thermal expansion can be suppressed.SELECTED DRAWING: Figure 1 (Grant)
