PURPOSE:The titled reaction material prevented from the compaction of a soft packing material while inhibiting the increase of pressure loss, characterized in that baffles are inserted into a packing layer comprising the soft packing material toward te direction at right angles to the stream of a liquid to be treated. CONSTITUTION:In a packing layer type reaction tower for producing a useful substance by using an immobilized bio-catalyst such as immobilized enzyme or an immobilized microorganism, baffles 4 are inserted into the reaction tower 1 toward the direction at right angles to the flow direction of a liquid to be treated at predetermined pitches. The spaces between the baffles are packed with the soft packing material 5 to form a packing layer. Each of the baffles 4 is formed into a circular, an oval, a triangular or a square shape or formed into a hollow shape and they are arranged in a parallel, zigzag or grid like state. When the liquid to be treated is flowed through this reaction tower 1, a desired void ratio is held and pressure loss is reduced and, therefore, a production amount per unit catalyst can be increased.
