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 to 34), lead wires (41 to 44) connected to the tip electrode (31) and the ring-shaped electrodes (32 to 34), respectively, and a pull wire (50) fixed to the tip electrode (31). The catheter shaft (10) is constituted of a shaft proximal end portion (11) formed of a metal tube having a spiral slit (115) formed in a tip portion, a shaft distal end portion (12) formed of a resin tube of multi-lumen structure, and a resin covering layer (13) covering outer peripheries of the shaft proximal end portion (11) and a rear end portion of the shaft distal end portion (12). The lead wires (41 to 44) and the pull wire (50) extend through different lumens of the resin tube constituting the shaft distal end portion (12). This electrode catheter can exhibit good kink resistance, torque transmissibility and pushability in the entire shaft.
