PROBLEM TO BE SOLVED: To provide a reversibly thermochromic hose having superior safety and sanitation properties of a hose itself and substances circulated in the hose, capable of being applied to various purposes, and having superior visibility and durability of thermochromic function, so that it has convenience that temperatures of the hose itself and the substances circulated in the hose can be clearly and permanently visually confirmed. SOLUTION: In this reversibly thermochromic hose, a reversibly thermochromic resin phase composed of at least a reversibly thermochromic composition composed of (a) electron-releasing coloring organic compound, (b) electron-receiving compound, (c) reaction medium for reversibly generating electron releasing/receiving reaction by the components (a) and (b) in a specific temperature zone, a light stabilizer, and a resin having a solubility parameter of 9 or more, exists in the hose composed of styrene thermoplastic elastomer.
