description	[Problem to be Solved]To provide a catheter capable of preventing collapse of the catheter tip even when inserted into a stenosis such as CTO or the like, and being inserted easily into the stenosis.[Solution to Problem]A catheter 1 comprises a catheter body 5, and a distal tip 3 joined to a distal end of the catheter body 5 and made of a resin including tungsten powder 2, wherein the distal tip 3 includes a distal region 7 and a proximal region 9 disposed in a proximal side of the distal region 7, and a hardness of the distal region 7 is higher than a hardness of the proximal region 9. Thus, the proximal region 9 has a followability to a medical device such as a guidewire and the like used together, the catheter 1 has an effect of improving insertability into the stenosis and an effect of preventing the collapse of the distal tip 3 of the catheter 1 when the catheter 1 is inserted into the stenosis.
