PROBLEM TO BE SOLVED: To provide a catheter which is used when a liquid is injected into a target region in the body from the outside, and which enables a temperature to be maintained until the liquid reaches the target region in the case of injection of the high-temperature or low-temperature liquid.SOLUTION: In a catheter 100, a shaft part 40 is provided with a heat exchange medium rumen 71 that passes through a heat exchange medium, and a heat-insulating rumen 81 that comprises a gas layer or a vacuum layer formed to cover the periphery of the heat exchange medium 1. This enables provision of the catheter capable of reducing heat release of the heat exchange medium until it reaches a target region. |
