    Abstract: A silent discharge plasma apparatus is disclosed which comprises the following components: a dielectric member (3); paired electrodes (1, 2) opposed against each other across the dielectric member (3); and an alternating-current source (6) adapted to apply an alternating-current voltage between the electrodes (1, 2) and to thus cause a discharge, such that a gas which is supplied to a discharge space (4) where a discharge should occur, will lead to plasma creation. At least one of the electrodes (1, 2) is formed by a conductive power feeding thin film which is formed on the dielectric member (3), such that when the dielectric member (3) is destroyed and an arc discharge develops between the electrodes (1, 2), the power feeding thin film on which the arc discharge develops is oxidized, such that creation of the arc discharge is stopped.
