Provided is an atherectomy catheter, including a cylindrical catheter body, a freely rotatable drive wire inserted into an inside of the catheter body, and a head for removing a thrombus, which is provided on a tip of the catheter body, in which the head has an elastic member formed of a material that is deformable by collision with the thrombus, and an outer surface of the elastic member is placed on substantially the same level as a surface of a blade for removing the thrombus, or protrudes outwardly from the surface of the blade. The outer surface of the elastic member is dented backward from the surface of the blade of a blade member, or concaved by collision with the thrombus, the blade then abuts on the thrombus present in the concave formed, and the thrombus is eliminated.
