PROBLEM TO BE SOLVED: To provide a filter device capable of changing the effective area of a filter member with simple constitution, a channel unit, a fluid supply device, and a fluid jetting device. SOLUTION: The filter device includes a filter chamber 44 provided in the middle of ink channels 47 and 48 going from an upstream side to a downstream side, the filter member 52 provided to be tensioned to divide the inside of the filter chamber 44 into the upstream side and the downstream side, and a pressure receiving part 54 constituting one wall surface of the filter chamber 44 and bent to displace according to pressure variation inside the filter chamber 44. The pressure receiving part 54 displaces to the inner side of the filter chamber 44 according to the pressure variation and abuts on the filter member 52, whereby the effective area of the filter member 52 is decreased.
