PROBLEM TO BE SOLVED: To provide a flocculater in a simple structure capable of obtaining a sufficient agitation function by utilizing the jetting action of a porous plate. SOLUTION: The flocculater 2 comprises the plurality of porous plates 3 disposed at an interval in the stream direction of raw water in the raw water of a flock forming basin 1, for which a direction orthogonal to the stream direction is a plate surface direction and many through-holes 4 are perforated on the plate surface, and a driving means 5 for moving the porous plates 3 back and forth along the stream direction, and the raw water is jetted and agitated by moving the porous plates 3 back and forth.
