Abstract

The present disclosure provides a means for preventing or suppressing the leaching of a redox mediator constituting a reagent layer in a probe of an embedded biosensor, in particular, a means capable of improving preservation stability (durability) while maintaining glucose measurement sensitivity. The high molecular weight redox polymer according to the present disclosure is represented by general formula (A1), wherein Xrepresents an anionic species; L represents a linker; Poly represents a high molecular weight polymer; and Rto Reach independently represent a hydrogen atom or a substituent. The biosensor according to the present disclosure has a working electrode, a counter electrode, a reagent layer disposed on the working electrode, and a protective film covering at least the reagent layer, and the reagent layer contains an oxidoreductase that oxidizes or dehydrogenates the analyte and at least one high molecular weight redox polymer represented by general formula (A1).
