The disclosed biosignal tetrode may include four electrodes extending in the bioinsertion direction and arranged symmetrically with each other, and an insulating layer surrounding the four electrodes to insulate the four electrodes. In addition, the disclosed method for manufacturing a biosignal measuring rod includes forming a first insulating layer, forming first and second electrodes on the first insulating layer, and second insulating layer on the first and second electrodes. And forming third and fourth electrodes on the second insulating layer, and forming a third insulating layer on the third and fourth electrodes. |
