<p><P>PROBLEM TO BE SOLVED: To provide a gas purification device purifying purification object gas by efficiently removing trapped PM without heating. <P>SOLUTION: The gas purification device 10 includes: a discharge electrode 32; a discharge counter electrode 33 provided to face the discharge electrode 32 through a dielectric body 31; and a dust collecting counter electrode 34 provided to face the discharge electrode 32 through a gas flow passage 36. A conductor pattern constituting the discharge electrode 32 is formed not to be free from a closed loop-forming part in which the circumference is surrounded by a conductor. The conductor pattern is constituted to satisfy the relation of S/D≥0.5, wherein S is a circular diameter S at the time when circular envelopes contact with each other in at least any one point when a circular envelope with the same diameter around an optional point on the conductor pattern is drawn while increasing the circular diameter, and D is the thickeness of the dielectric body 31 between the discharge electrode 32 and the discharging counter electrode 33. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
