Medical guide wire and manufacturing method of medical guide wire

A medical guide wire, comprising:

• a core that has a portion tapered in diameter from a proximal end side to a distal end side;
• and
• an outer coil into which the distal end side of a core distal end portion of the core is inserted, wherein
• a distal joining section is provided on a distal end portion of the outer coil and a proximal joining section is provided on a proximal end portion of the outer coil, the distal joining section being connected with the core distal end portion,
• the outer coil includes a coil inclined portion on the distal end side,
• the distal joining section includes the coil inclined portion;
• the coil inclined portion is flat-shaped having a first minor axis and a first major axis when the coil inclined portion is viewed from the distal end side along a direction extending a center line of the outer coil, and each one turn of the coil wire of the coil inclined portion is continuously inclined in one direction along a center line of the outer coil,
• the distal joining section is formed by connecting the coil inclined portion with a tip of the core distal end portion by a joint member, the distal joining section having an elliptic shape having a second minor axis and a second major axis when the distal joining section is viewed from the distal end side along the direction extending the center line of the outer coil,
• a direction of the first minor axis in the flat-shaped coil inclined portion is same as a direction of the second minor axis in the distal joining section when the coil inclined portion and the distal joining section are viewed from the distal end side along the direction extending the center line of the outer coil, and
• a direction of the first major axis in the flat-shaped coil inclined portion is same as a direction of the second major axis in the distal joining section when the coil inclined portion and the distal joining section are viewed from the distal end side along the direction extending the center line of the outer coil.
