Abstract
A measurement apparatus including a lining body and an electrode. The electrode includes an electrode head portion having a first surface to contact a measurement object and a second surface opposite to the first surface, an electrode anchor portion formed around a peripheral portion of the second surface, and an electrode shaft portion. A protruding portion having a semicircular cross-section and a size smaller than a radius of the electrode shaft portion is formed around a peripheral edge portion of the second surface. A counterbore flat surface portion is formed in the lining body to define an arc portion of the inner surface as a flat surface, and while uniformly coming into contact with the counterbore flat surface portion of the lining body with pressure, the protruding portion of the electrode anchor portion bites into the counterbore flat surface portion.
