Abstract: Provided are a recording and/or stimulation neural electrode that is flexible and can be tightly attached to the brain surface, and shows no deterioration in adhesiveness even when embedded for a long period of time; and a method using such neural electrode. A neural electrode of the present invention includes an attaching part having at least:



an insulating sheet whose one surface serves as an attaching surface to be attached to the brain surface; and
a conductive wiring formed on a surface of the insulating sheet that is opposite to the attaching surface, wherein
multi-point electrode parts of the conductive wiring are exposed from hole parts of the insulating sheet, and wherein
the insulating sheet is an elastomer thin film having a thickness of 2 to 100 μm, and the conductive wiring has a thickness of 10 μm or smaller.
