The invention provides a vacuum valve capable of driving an arc generated between electrodes in a circumferential direction without stagnation at a specific position when the vacuum valve is opened (when a pair of electrodes is separated). The present invention is characterized by having a pair of electrodes (E1, E2) which are positioned at positions facing each other so as to be capable of contact and separation, and which are provided with electrode facing surfaces (E1s, E2s) partitioned by a plurality of grooves (12, 13), the current density of facing regions (8a, 10a) adjacent to the electrode facing surfaces being higher than the current density outside the facing regions among the pair of electrodes. 本发明提供一种真空阀，在真空阀的开放时(使一对电极分离时)，能够使在电极彼此之间产生的电弧不停滞在特定位置而沿着圆周方向驱动。具有一对电极(E1、E2)，该一对电极被定位于以能够接触分离的方式对置的位置，具备由多个槽部(12、13)划分的电极对置面(E1s、E2s)，在一对电极中，与电极对置面邻接的对置区域(8a、10a)的电流密度高于对置区域以外的电流密度。
