摘要：
A bio-electrode includes an electro-conductive base material and a living body contact layer. The living body contact layer includes a water-free resin layer and a permeation layer on a surface side of the resin layer where a living body comes into contact. The permeation layer is permeated with water and a water-soluble salt selected from the group consisting of sodium salts, potassium salts, calcium salts, magnesium salts, and betaines. This aims to provide: a dry-type bio-electrode that enables quick signal collection after attachment to skin, the bio-electrode being excellent in electric conductivity and biocompatibility, light-weight, and manufacturable at low cost, and capable of preventing significant reduction in the electric conductivity even when wetted with water or dried; a method for manufacturing the bio-electrode; and a method for measuring a biological signal.
