An analytical element for analysis of a liquid having an interconnected void structure zone positioned on one side of a liquid-impermeable, light-transmissive support, being characterized in that said interconnected void structure zone comprises a bound particulate structure which is a three-dimensional lattice, being non-swellable in the liquid and having interconnected voids with a void volume of 25 to 85% among the particles to provide transport of said liquid, the material for said bound particulate structure being non-swellable in and impermeable to said liquid and said bound particulate structure being constituted of heat-stable, organic polymer particle units having reactive groups with particle sizes of 1 to 350 microns which are chemically bonded directly to each other through said reactive groups in the areas of contact. A method of analysis utilizing the analytical element in immunoassay is also disclosed.
