| 1. A dry analytical element comprising a support, at least one reaction layer containing a color indicator and at least one
spreading layer containing a substrate provided on said support in this order, said spreading layer further containing at
least one surfactant selected from surfactants that substantially do not destroy blood platelet, said surfactant being selected
from the group consisting of silicon series surfactants,
wherein said silicon series surfactant is at least one selected from compounds shown by following general formulae (1) to
(4):
 in which Z represents an organic group represented by the general formula —R—( C2H4O )a—(C3H6O )bR.
