PROBLEM TO BE SOLVED: To provide a bioelectrode through which burden during mounting is small and by which a high quality biological signal can be stably obtained.SOLUTION: A bioelectrode includes: a biological signal receiving part 10 consisting of a conductive porous body or a non-conductive porous body in which a good conductive material or an unpolarized material is fixed to at least a part of the surface and inside thereof a connector part 12 electrically connected with the biological signal receiving part 10 and a moisture evaporation suppression cover 11 for covering an opposite surface to a surface being in contact with a living body of the biological signal receiving part 10. The biological signal receiving part 10 is impregnated with an electrolyte solution or a non-electrolyte liquid 14.
