ABSTRACT:
A multilayer analytical element for analysis of analyte in a liquid sample comprising a liquid sample-spreading layer, a reagent layer containing a diazonium salt, and a liquid-impermeable light-transmissive support, being laminated in this order, in which said reagent layer contains a sulfonic acid group-containing polymer having at least 10 molar % of a repeating unit selected from those consisting of a sulfoalkyl group and sulfophenyl group. The analytical element can be an element comprising a porous reagent layer containing a diazonium salt and the liquid-impermeable light-transmissive support, being laminated in this order.
