In a guide wire (1), a core line (2) has a proximal side wire (4) and a distal side wire (5), the latter of which is to be connected to a front end of the proximal side wire (4). The distal wire (5) is smaller in rigidity and superior in restitution than the proximal side wire (4). A concave portion (51) is provided on either the distal end surface of the proximal side wire (4) or a proximal end surface of the distal side wire (5). A convex portion (41) is provided on the other side wire among the distal end surface of the proximal side wire (4) and the proximal end surface of the distal side wire (5) The concave portion (51) and the convex portion (41) are interfit together, and pressure bonded by means of swaging or drawing procedure. This enables a manufacturer to sufficiently bond the distal side wire (5) and the proximal side wire (4) at a portion terminated in less than 100 mm from a distal end (11) of the guide wire (1), thus imparting a good restitution to the distal end (11) with a good supportability and torque-transmission maintained respectively.
