[problem] guide to maintain the wire passage of in the lesion of achieving a reduction in the back shadow of the tomographic image while, guide wire or the like that can be recognized symptoms of the exact lesion on the basis of the sharpening tomographic image to provide. A guide wire 1, core wire to the tip from the rear end, and a core wire tip small-diameter portion 26 core rear end large-diameter portion 21 and the core intermediate small-diameter portion 25. Core intermediate small-diameter portion 25, while rotating the probe provided in the image diagnostic catheter within the sheath is located within retract into the rear end side. The hydrophilic coating film 6 formed on the outer periphery of the core wire the intermediate small-diameter portion 25 absorbs water to swell, since the film thickness is extremely small light absorption by water is also increased, it is added increased thickness content dark of back shadow will not be extended. Then, to lower the dynamic friction coefficient due to the hydrophilic coating 6 swollen, drastically improve the sliding properties.FIELD 3
