A dry type multilayer analysis element comprises at least one porous medium layer comprising a membrane filter, to which an antigen (or antibody) is immobilized, and at least one reagent layer through which a substance(s) which did not participate in an antigen-antibody reaction can permeate. The multilayer analysis element is effective for assaying components present in body fluids, blood, urine, etc., in a simple manner.
