<p>An electrode catheter is provided with: a catheter shaft (10); an operating handle (20) provided with a connector (70); a tip electrode (31); ring-shaped electrodes (32-34); lead wires (41-44) connected to the tip electrode (31) and the ring-shaped electrodes (32-34), respectively; and a pull wire (50) affixed to the tip electrode (31). The catheter shaft (10) comprises: a shaft proximal end section (11) comprising a metallic tube; a shaft distal end section (12) comprising a resinous tube; and a resinous coating layer (13) for covering the outer peripheries of both the shaft proximal end section (11) and the shaft distal end section (12). A lead wire protective tube (61) which comprises a soft tube and a wire protective tube (62) which comprises a soft tube are inserted in the shaft proximal end section (11). In the electrode catheter, the lead wires extending from the shaft proximal end section into the operating handle are not damaged or broken by coming into contact with the edge of the opening end of the shaft proximal end section.</p> |
