1. A lead implanted in a body to apply electrical stimulation to body organs, the lead comprising:
an electrode wire having one end provided as an insertion portion to be inserted into a body and another end provided as an interface portion for connection with an external device to transmit a stimulation signal to body organs into which the lead is inserted;
a plurality of first electrodes in the insertion portion to transmit electrical stimulation to body organs;
a plurality of second electrodes on the interface portion to receive electrical stimulation applied from outside; and
a plurality of signal lines configured to interconnect the first electrodes and the second electrodes, respectively, and transmit the electrical stimulation received by the second electrodes to the first electrodes,
wherein the insertion portion of the electrode wire comprises a plurality of support portions on which the first electrodes are respectively disposed and a plurality of stretchable portions between the support portions and expandable and contractible,
and further comprises an operation unit for pushing or pulling each support portion in a longitudinal direction of the electrode wire,
wherein, by pushing or pulling each support portion, a stretchable portion between the support portions is stretched and contracted to adjust a position of the support portion.
