Abstract
A catheter is disclosed which has at least a two-layered structure and can suppress decrease in function thereof by suppressing the disorder at an interface between layers during use, and a method for manufacturing the same. The catheter has an inner layer as a tube shaped body made of a thermoplastic resin and an outer layer, as a tube shaped body made of a thermoplastic resin, coming into contact with the outer surface of the inner layer, and has a reinforcement member which is at least partially embedded in the inner layer and includes a gap leading the inner layer toward the radial outside of the catheter. The inner layer has a protrusion which extends in an axial direction of the catheter while protruding from the gap to the radial outside, is positioned on the radial outside of the reinforcement member, and ingrows into the outer layer.
