To provide a guide wire having its coil body covered with a hydrophilic coating film capable of exhibiting sufficient lubricity even in a situation where there is little moisture in its surroundings. In a coil-type guide wire (1), coating portion (10) is formed by stacking a plurality of films where film (10a) of the lowermost layer is a hydrophobic film and the film of the top layer thereof is hydrophilic film (10b). Furthermore, film (10a) of the lowermost layer of coating portion (10) is arranged to come between wires (7) of coil body (6) and spaces (20) are formed between film (10b) of the top layer thereof and the sections where the film (10a) is arranged between the wires. Due to forming the spaces (20), it is possible to pool moisture in the spaces (20) and in cases when moisture in the surroundings thereof becomes less, it is possible to supply the moisture pooled in the spaces (20) to hydrophilic film (10b). As a result, even in a situation where there is little moisture in the surroundings, is becomes possible to exhibit a sufficient amount of lubricity.
