摘要： 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 1 of the present invention is such that its attaching part 2 which is a sheet-shaped electrode is to be attached to the brain surface upon use, wherein
the attaching part has at least:
an insulating sheet 3 whose one surface serves as an attaching surface to be attached to the brain surface; and
a conductive wiring 4 formed on a surface of the insulating sheet that is opposite to the attaching surface, wherein

multi-point electrode parts 4a of the conductive wiring are exposed from hole parts 3a 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.
