A percutaneous catheter (30, 60, 90) through which blood can pass and which expands in an axial direction in response to a dilator being inserted through the percutaneous catheter (30, 60, 90), comprising: a catheter tube (31, 131) that extends in the axial direction; and a distal tip that is provided on a distal side of the catheter tube (31, 131) and is configured to allow the dilator to be attached to the distal tip, wherein the catheter tube (31, 131) includes a non-coated portion (32, 232) which is provided on a proximal side of the distal tip and is formed of wires braided in an intersecting manner, and a coating portion (33, 133) which is provided on the proximal side of the non-coated portion (32, 232) and is formed by coating the wires braided in an intersecting manner with a resin material, wherein an inner diameter of the non-coated portion (32, 232) is configured to be larger than an outer diameter of the dilator before the dilator is inserted through the percutaneous catheter (30, 60, 90), and wherein when the dilator is inserted through the percutaneous catheter (30, 60, 90), the non-coated portion (32, 232) expands in the axial direction and is reduced in inner diameter so that an inner peripheral portion of the non-coated portion (32, 232) comes into tight contact with an outer peripheral portion of the dilator, wherein the coating portion (33, 133) has a distal portion (134, 331) which is provided on the distal side, and a proximal portion (135, 332) which is provided on the proximal side of the distal portion (134, 331) and has flexibility lower than flexibility of the distal portion (134, 331), wherein an inner diameter of the distal portion (134, 331) is configured to be larger than the outer diameter of the dilator before the dilator is inserted through the percutaneous catheter (30, 60, 90), and wherein when the dilator is inserted through the percutaneous catheter (30, 60, 90), the distal portion (134, 331) expands in the axial direction and is reduced in inner diameter so that an inner peripheral portion of the distal portion (134, 331) comes into tight contact with the outer peripheral portion of the dilator. a catheter tube (31, 131) that extends in the axial direction; and a distal tip that is provided on a distal side of the catheter tube (31, 131) and is configured to allow the dilator to be attached to the distal tip, wherein the catheter tube (31, 131) includes a non-coated portion (32, 232) which is provided on a proximal side of the distal tip and is formed of wires braided in an intersecting manner, and a coating portion (33, 133) which is provided on the proximal side of the non-coated portion (32, 232) and is formed by coating the wires braided in an intersecting manner with a resin material, a non-coated portion (32, 232) which is provided on a proximal side of the distal tip and is formed of wires braided in an intersecting manner, and a coating portion (33, 133) which is provided on the proximal side of the non-coated portion (32, 232) and is formed by coating the wires braided in an intersecting manner with a resin material, wherein an inner diameter of the non-coated portion (32, 232) is configured to be larger than an outer diameter of the dilator before the dilator is inserted through the percutaneous catheter (30, 60, 90), and wherein when the dilator is inserted through the percutaneous catheter (30, 60, 90), the non-coated portion (32, 232) expands in the axial direction and is reduced in inner diameter so that an inner peripheral portion of the non-coated portion (32, 232) comes into tight contact with an outer peripheral portion of the dilator, wherein the coating portion (33, 133) has a distal portion (134, 331) which is provided on the distal side, and a proximal portion (135, 332) which is provided on the proximal side of the distal portion (134, 331) and has flexibility lower than flexibility of the distal portion (134, 331), wherein an inner diameter of the distal portion (134, 331) is configured to be larger than the outer diameter of the dilator before the dilator is inserted through the percutaneous catheter (30, 60, 90), and wherein when the dilator is inserted through the percutaneous catheter (30, 60, 90), the distal portion (134, 331) expands in the axial direction and is reduced in inner diameter so that an inner peripheral portion of the distal portion (134, 331) comes into tight contact with the outer peripheral portion of the dilator.
