Abstract
It is an object of the invention to provide a multilayer analytical element having a porous where the property of the film is maintained and which is free from the liquid-amount dependency even in the case where a porous film is laminated. The present invention provides a dry multilayer analytical element for the analysis of a liquid sample which comprises a water-non-transmitting planar support on one side of which at least one functional layer and a porous liquid-sample-developing layer consisting of at least one non-fibrous porous are integrally layered in the mentioned order, wherein the non-fibrous porous film contains a water-soluble polymer in such a manner that it does not interact with the functional layer.
