A catheter having multiple curvatures and forming bending by adjusting a wire, the catheter comprising: a first elastic member positioned at an end portion of the catheter and provided in a flat form; a second elastic member connected with the first elastic member and curved with a first radius of curvature to protrude toward a first direction; a first wire connected with a first surface of the first elastic member, and configured to pull the catheter to bend the catheter in the first direction; a second wire connected with a second surface of the first elastic member, which is opposite to the first surface, connected with the first wire and configured to pull the catheter to bend the catheter in a second direction; and a tube containing the first elastic member, the second elastic member, the first wire, and the second wire, further comprising: a third elastic member connected with the second elastic member and provided in a flat form or curved with a third radius of curvature to protrude toward the first direction; a fourth elastic member connected with the third elastic member and curved with a fourth radius of curvature to protrude toward the first direction or the second direction; a third wire connected with a first surface of the third elastic member; and a fourth wire connected with a second surface of the third elastic member, which is opposite to the first surface of the third elastic member, connected with the third wire. a first elastic member positioned at an end portion of the catheter and provided in a flat form; a second elastic member connected with the first elastic member and curved with a first radius of curvature to protrude toward a first direction; a first wire connected with a first surface of the first elastic member, and configured to pull the catheter to bend the catheter in the first direction; a second wire connected with a second surface of the first elastic member, which is opposite to the first surface, connected with the first wire and configured to pull the catheter to bend the catheter in a second direction; and a tube containing the first elastic member, the second elastic member, the first wire, and the second wire, further comprising: a third elastic member connected with the second elastic member and provided in a flat form or curved with a third radius of curvature to protrude toward the first direction; a fourth elastic member connected with the third elastic member and curved with a fourth radius of curvature to protrude toward the first direction or the second direction; a third wire connected with a first surface of the third elastic member; and a fourth wire connected with a second surface of the third elastic member, which is opposite to the first surface of the third elastic member, connected with the third wire. a third elastic member connected with the second elastic member and provided in a flat form or curved with a third radius of curvature to protrude toward the first direction; a fourth elastic member connected with the third elastic member and curved with a fourth radius of curvature to protrude toward the first direction or the second direction; a third wire connected with a first surface of the third elastic member; and a fourth wire connected with a second surface of the third elastic member, which is opposite to the first surface of the third elastic member, connected with the third wire.
