A catheter (10) has a main lumen (20), and sub-lumens (30) each of which having a diameter smaller than that of the main lumen (20). The plurality of sub-lumens (30) are arranged along a circumference of the main lumen (20) in a discrete manner, and each of the sub-lumens (30) has an operating wire (40), fixed to the distal end section (15) of the catheter (10), laid therethrough in a freely slidable manner. By pulling the operating wire(s) (40) respectively laid through the sub-lumens (30), the distal end section (15) of the catheter (10) may be bent towards the pulled operating wire(s) (40) laid therethrough.
