[Problem] To provide a percutaneous catheter which is capable of: reducing pressure loss of a liquid circulating in a circulation circuit ensuring the required flow rate of the liquid, without increasing invasiveness or the burden on the body of a patient and inhibiting displacement of the position of the tip of the percutaneous catheter after the percutaneous catheter has been inserted into a living organism. [Solution] This percutaneous catheter 30 is provided with: a first tube 32 and a second tube 33 which is provided to the base end side of the first tube in the insertion direction, is provided with a smaller inner diameter than the first tube, and has a lower stretchability than the first tube. The first tube is provided with a first reinforcement body 321 comprising wires W which are braided so as to intersect each other. The second tube is provided with a second reinforcement body 331 comprising wires which are braided so as to intersect each other. The first reinforcement body is formed such that the braiding angles, i.e. the internal angles in the axial direction among the angles formed by the intersecting wires, are smaller than those of the second reinforcement body.Le problème décrit par la présente invention est de fournir un cathéter percutané qui est apte : à réduire la perte de pression dun liquide circulant dans un circuit de circulation à assurer le débit requis du liquide, sans augmenter le caractère effractif ou la charge sur le corps dun patient et à empêcher le déplacement de la position de la pointe du cathéter percutané après que le cathéter percutané ait été inséré dans un organisme vivant. La solution selon linvention porte sur un cathéter percutané (30) comprend : un premier tube (32) et un second tube (33) qui est disposé sur le côté dextrémité de base du premier tube dans le sens dinsertion, est doté dun diamètre interne inférieur à celui du premier tube, et a une extensibilité inférieure à celle du premier tube. Le premier tube est
