A multilayer analytical element for quantitative analysis of bilirubin in a liquid sample by a diazo method, which comprises a laminated structure consisting essentially of:
(1) a porous reagent layer containing an acidic binder and a diazonium salt being reactive to bilirubin to produce azobilirubin;
(2) an absorbent layer capable of absorbing an excessive liquid portion; and
(3) a liquid-impermeable light-transmissive support.
