  An adhesive composition including resin and electro-conductive material, wherein the electro-conductive material is one or more salts from sodium salt, potassium salt, and calcium salt of fluorosulfonic acid having 5 or more carbon atoms shown by the general formula (1): (R 1 —X—Y—SO 3 − ) n M n+ (1), wherein, R 1 represents a monovalent hydrocarbon group having 1-30 carbon atoms and optionally substituted by a heteroatom or optionally interposed by a heteroatom; X represents any of a single bond, ether group, ester group, and amide group; Y represents a linear or branched alkylene group having 2-4 carbon atoms, containing 1-6 fluorine atoms, and optionally containing a carbonyl group; M n+ represents any of a sodium ion, potassium ion, and calcium ion. This can form a living body contact layer for a bio-electrode with electric conductivity, biocompatibility, and light weight, which can be manufactured at low cost and without electric conductivity large lowering even when wetted with water or dried.

  An adhesive composition including a resin and electro-conductive material, wherein the electro-conductive material is an ammonium salt of fluorosulfonic acid having 5 or more carbon atoms shown by the general formula (1): (R 1 —X—Z—SO 3 − ) n M n+ (1), wherein, R 1 represents a monovalent hydrocarbon group having 1 to 40 carbon atoms and optionally substituted by a heteroatom or optionally interposed by heteroatom; X represents any of a single bond, ether group, ester group, and amide group; Z represents an alkylene group having 2 to 4 carbon atoms, containing 1 to 6 fluorine atoms, and optionally containing a carbonyl group; M + represents a cation having one or two ammonium cation structures. This can form a living body contact layer for a bio-electrode with excellent electric conductivity, biocompatibility, and light weight, which manufactures at low cost and does not cause large lowering of the electric conductivity even when it is wetted with water or dried.
