Abstract:
An electrode according to one aspect of the present invention is formed on a base material composed of a ceramics. The electrodes includes a matrix composed of an Ni—Cr alloy (with a Cr content of 20 to 60 wt. %) or an MCrAlY alloy (M is at least one material selected from Fe, Co and Ni), and a disperse phase that is dispersed in the matrix and composed of an oxide mineral having a laminated structure. The ratio of area occupied by the disperse phase in a cross section of the electrode is 40 to 80%. With the structure like this, it is possible to suppress the increase in the electrical resistance even after a thermal cycle is performed.
