To provide a thrombus suction catheter with excellent crossability, capable of suctioning atheroma, reaching a sharply-curved affected area and passing through a narrowed section of the blood vessel. A thrombus suction catheter is a tubular device comprising a catheter body (1) with a thrombus suction lumen (11) and a guide wire lumen (13); and a connector (2) provided on a proximal end of the catheter body. The thrombus suction lumen 11 has a suction port (12) in a sidewall of a tip of the catheter body and passes through the catheter body to a proximal end of the catheter body, while the guide wire lumen (13) has a guide wire insertion port (14) in the sidewall of the tip and passes through the tip along a longitudinal axis of the catheter body. The suction port 12 and the guide wire insertion port 14 are formed on the sides opposite to one another with respect to the longitudinal axis of the catheter body.
