More Information
Summary:A guide wire includes a first core shaft, a second core shaft, a covering member, and joint layer. The first core shaft has a first large-diameter portion and a first small-diameter portion, and the second core shaft has a second large-diameter portion and a second small-diameter portion. The covering member covers a contact portion where the first and second small-diameter portions are arranged oppositely to each other, and at least a part of each of the first and second small-diameter portions adjacent to the contact portion. The joint layer joins the covering member with the first and second small-diameter portions inside the covering member. A length of the covering member is shorter than a sum of the lengths of the first and the second small-diameter portion in the axial direction, and longer than the shorter of the lengths of the first and second small-diameter portions in the axial direction.
