PROBLEM TO BE SOLVED: To provide a forming structure of an adhesive layer by which the surface of a tube member to be adhered can be easily improved in quality, and the filling condition of an adhesive can be easily managed by making the tips of tube members flexible or short (margin to connect) in the case of making a tube member forming a shaft of a balloon catheter and a tube member forming a balloon adhere to each other. SOLUTION: In a balloon catheter formed by plural tube members co-axially superposed inside and outside in the radial direction, an adhesive layer 8 concerned with adhesion between the end part of one tube member (the base end side sleeve 6 of a balloon 2, a forward end side sleeve 7) positioned outside and the other tube member (outer tube 4, inner tube 5) positioned inside is formed continuously extending from one end of the other tube member to the outer peripheral side of the end of one tube member. |
