  The present invention provides a bio-electrode composition including a polymer compound having both an ionic repeating unit A and a (meth)acrylate repeating unit B, wherein the ionic repeating unit A is a repeating unit selected from the group consisting of sodium salt, potassium salt, and ammonium salt having either or both partial structures shown by the following general formulae (1-1) and (1-2), and the (meth)acrylate repeating unit B is a repeating unit shown by the following general formula (2). This can form a living body contact layer for a bio-electrode with excellent electric conductivity, biocompatibility, and light weight, which can be manufactured at low cost and does not cause large lowering of the electric conductivity even when it is wetted with water or dried.

  The present invention provides a biomedical electrode composition capable of forming a living body contact layer for a biomedical electrode that is excellent in conductivity and biocompatibility, is light-weight, can be manufactured at low cost, and can control significant reduction in conductivity even though the biomedical electrode is soaked in water or dried. The present invention was accomplished by a biomedical electrode composition including a polymer compound having both the ionic repeating unit “a” and the repeating unit “b” of (meth)acrylate, in which the ionic repeating unit “a” is a repeating unit of sodium salt, potassium salt, or ammonium salt including a partial structure represented by the following general formula (1), and the repeating unit “b” of (meth)acrylate is a repeating unit represented by the following general formula (2).
