The catheter may include a first hollow body having an inner lumen, and a second hollow body covering an outer periphery of the first hollow body and having an outside lumen between the first hollow body and the second hollow body. The outside lumen is divided by partition walls connected to the first hollow body and the second hollow body to form a plurality of outer lumens. On an outer periphery of the second hollow body, holes are formed for the respective outer lumens along a circumferential direction of the second hollow body.
