|発明の名称||ELECTRODE AND BIOSENSOR|
PROBLEM TO BE SOLVED: To provide an electrode measurable even in a small amount or low concentration sample and a biosensor having the electrode.
SOLUTION: An electrode according to one embodiment of the current invention is used as at least either an oxidation electrode causing electrolyte solution oxidation-reduction reaction or a reduction electrode, and includes: an insulating substrate having at least a projection or a recess on the surface; and a conductive electrode part which has a contact area for contacting the electrolyte solution and is formed in the way that it covers at least a part of the surface of the substrate. A topmost surface of the electrode is at a lower position than the topmost surface of the substrate by the projection or the recess in the state that the surface of the substrate faces upward, a space with a part above open is present above the contact area, and when used as either the oxidation electrode or reduction electrode, the contact area faces the other electrode used as the other via the space.
