摘要: A plasma generating electrode (1) having two or more plate-shaped unit electrodes (2) opposed to each other and adapted generate a when voltage is applied between the (2). At least one of includes ceramic dielectric body (3) where at surfaces has grooves (5) and/or recesses conductive film (4) provided inside (3). When (2), edge potions (9) formed by surface side recesses, density higher than that generated except for portions its vicinities can be generated.
