PROBLEM TO BE SOLVED: To provide a resin hose capable of sufficiently securing a flow rate of a fluid circulated through a resin hose, while securing the degree of freedom of hose arrangement.SOLUTION: A resin hose (10) includes: perfect circle parts (11, 14 and 16) that each have a channel assuming a perfect circle shape; and a flat part (13) which has a flat channel, which has a channel cross-sectional area (Sb) equal to or larger than channel cross-sectional areas (Sa and Sc) of minimum inside diameter parts of the perfect circle parts (11, 14 and 16), in which a short width (Db2) of the flat channel is smaller in dimension than inside diameters (Da and Dc) of the minimum inside diameter parts, and in which a long width (Db1) of the flat channel is larger in dimension than the inside diameters (Da and Dc) of the minimum inside diameter parts. |
