1. An implantable lead having adjustable electrode locations, comprising:
a main body having an upper part and a stepped lower part, the lower part having a narrower diameter than the upper part;
a plurality of first electrodes exposed and formed in the upper part of the main body at given intervals;
a plurality of second electrodes coupled to, and configured to move up and down with respect to, the stepped lower part of the main body and configured to deliver a stimulus signal to a core area into which the lead is inserted; and
a plurality of signal lines embedded in the main body and configured to connect the first electrodes and the second electrodes in a one-to-one manner,
wherein the lower part includes a slot for coupling with the second electrodes and enabling the second electrodes to move up and down, and
wherein the plurality of second electrodes are individually movable along the slot by an external force acting on the signal lines, thereby adjusting the locations of the second electrodes in the lower part.
