摘要：A guidewire includes a core shaft and a coil. The core shaft has a diameter thatdecreases from a proximal end portion toward a distal end portion, and the coil is woundaround an outer periphery of the distal end portion. The distal end portion includes amost distal end portion that is positioned at a most distal end of the distal end portion,
and an intermediate portion that is connected to the most distal end portion. The cross-sectional shape of the most distal end portion is a rectangular shape. The cross-sectionalshape of the intermediate portion gradually changes from the rectangular shape to acircular shape in a direction from the most distal end portion toward the proximal endportion. The length of the most distal end portion is shorter than the length of theintermediate portion.
