An analytical element to measure a specific component in a fluid samples comprising support, a layer containing a reagent provided the support and a spreading layer provided on above the reagent containing layer. In the spreading layer, an emzyme necessary for the reaction to produce a product capable of being detected with said reagent from the specific component is contained. The enzyme is protected from deterioration of activity during a manufacturing and preservation of the analytical element by means of the enzyme is included in the spread layer as a dispersion mixture with a protein and/or polypeptide. An accurate analytical result is stably obtained by the analytical element.
