Claim 7:
8. A guidewire comprising:
a core shaft;
a coil body covering a distal end portion of the core shaft; and
a coating agent covering an outer periphery of the coil body, wherein
the coil body includes a distal coil body disposed on a distal side of the coil body, and a proximal coil body disposed on a proximal side of the distal coil body,
a surface roughness of the proximal coil body is higher than a surface roughness of the distal coil body,
an outer diameter of the distal coil body not including the coating agent is equal to an outer diameter of the proximal coil body not including the coating agent, and
the outer diameter of the proximal coil body plus a thickness of the coating agent on the outer periphery of the proximal coil body is greater than the outer diameter of the distal coil body plus a thickness of the coating agent on the outer periphery of the distal coil body.
