PROBLEM TO BE SOLVED: To provide a disc filter device in which the shape of the center liquid collecting channel is arbitrarily designed and which can be produced and processed easily without deteriorating the positioning and supporting function of a filter element, and more particularly to provide a disc filter device with an improved center post. SOLUTION: The disc filter device provided is characterized in that the center post of the device is composed of a hollow outer cylinder and a solid inner cylinder to be inserted into the outer cylinder: that a filtrate flow-in port communicated to a filtrate flow-out port of a hub is formed in the outer cylinder: and that the center liquid collecting channel is formed between the outer cylinder and the inner cylinder.
