Patent ID: 8128884

Claim:
A plasma reactor comprising: a stack ( 104 ) constructed by sequentially stacking plus electrodes ( 101 ) and minus electrodes ( 102 ) and spacers ( 103 ), each of the plus and minus electrodes ( 101 , 102 ) including a conductive electrode, which includes a main electrode portion ( 115 ) and is insulated from neighboring plus and minus electrodes ( 101 , 102 ) of opposite polarity, a vertical connection electrode ( 111 ) for connecting each of the plus and minus electrodes ( 101 , 102 ) to neighboring plus and minus electrodes ( 101 , 102 ) of same polarity; a reactor body ( 105 ) provided at only a single lateral side of the stack ( 104 ) to hold the stack ( 104 ) from the single lateral side among multiple lateral sides of the stack; deformation preventing means ( 107 ) disposed at each of said plus and minus electrodes ( 101 , 102 ) to disperse stress of the plus and minus electrodes ( 101 , 102 ) and relieve a local thermal stress buildup thermal expansion and contraction; and a first external terminal ( 108 ) provided on the reactor body ( 105 ) for electrically connecting the plus electrodes ( 101 ), and a second external terminal ( 109 ) provided on the reactor body ( 105 ) for electrically connecting the minus electrodes ( 102 ); wherein the plus electrodes ( 101 ) and the minus electrodes ( 102 ) are arranged alternately with spacers ( 103 ) there-between to define passages ( 106 ) through which gas is allowed to pass, and a projection ( 110 ) is formed on a surface of the reactor body ( 105 ) in a direction perpendicular to a stack direction of the stack ( 104 ) for fixing the plasma reactor ( 100 ) to a case.
