An electrode assembly for a conductivity meter or resistivity meter includes: an electrode main body; a test liquid intake flow path passing through the electrode main body; a pair of voltage electrodes which is respectively provided so that surfaces thereof are exposed to opposing inner wall surfaces forming the test liquid intake flow path; and a pair of current electrodes which is respectively provided so that surfaces thereof are exposed to each of the inner wall surfaces, and in this configuration, each of the pair of current electrodes contains a carbon-based material, and each of the surfaces of the pair of current electrodes exposed to the inner wall surfaces is in a strip shape.

Provided is an electromagnetic sensor capable of stably measuring electric conductivity and the like even in the case where solid matters are mixed in a sample solution. The electromagnetic sensor includes a substrate, a through hole formed in the substrate, an electrode attached to a surface of the substrate, and a housing that covers the through hole and the electrode, and in this configuration, the sample solution supplied to a surface of the substrate opposite to the surface of the substrate having the electrode attached thereto is allowed to flow into the housing from the through hole and to be accommodated in the housing, so that the sample solution is allowed to be in contact with the electrode.
