Provided is an endoscopic duct cleaning tool which uses elastic porous members to prevent the inside of a duct of an endoscope from being damaged, and which can firmly fix the elastic porous members to a core wire and secure a sufficient thickness in each of the elastic porous members. This endoscopic duct cleaning toolis inserted into a ductof an endoscopeto clean the duct. The endoscopic duct deviceincludes a core wireconsisting of a stranded wire, plural cylindrical elastic porous membersdisposed at certain intervals and at certain places in an axial direction of the core wireso as to cover an outer circumference of the core wiredirectly, and resin tubescovering outer circumferences of portions of the core wirewhich are not covered with the elastic porous members. An outer diameter of each of the resin tubesis formed to be larger than an inner diameter of each of the elastic porous members. A frontmost end tubeand a basemost end tubedisposed in a frontmost end portion and a basemost end portion of the core wirerespectively are fixedly attached to the core wire
