A disposable skin surface dry electrode used in the field of medical appliances, and a manufacturing method therefor. The dry electrode comprises a flexible PCB base material (1), and an electrode micro-needle array (2) and a metal button that are respectively arranged on the upper surface and the lower surface of the flexible PCB base material (1). A conducting medium for conducting the electrode micro-needle array (2) and the metal button is arranged penetrating the flexible PCB base material (1). The electrode micro-needle array (2) is manufactured on the flexible PCB base material (1) by using a matured electroplating process rather than a micro-machining process, so the cost is low, no hydrofluoric acid is used, and volume production is applicable. The dry electrode is manufactured on the flexible PCB rather than substrates such as silicon and metal, so the dry electrode is flexible. The dry electrode in use is directly attached to the skin surface of a user without causing pain or bleeding, so the comfort level of the user and the signal collection stability can be improved, and the skin electrode contact noises are reduced. Meanwhile, compared with a wet electrode, the dry electrode is more convenient and rapid to use as no skin pre-treatment is needed.La présente invention concerne une électrode sèche à surface de peau jetable utilisée dans le domaine des appareils médicaux, et son procédé de fabrication.
