PROBLEM TO BE SOLVED: To aim a thin-shaping of an electrode, and furthermore, an improvement in accrual rate of the electrode in a dust collector forming the resinous electrode by a die. SOLUTION: One or both of a pair of electrodes (40, 50) arranged in an air passageway (23) are constituted by the resin electrode formed by the die. Gradients (42a, 45a, 55a, 52a) are formed on the resin electrodes (40, 50) respectively at both sides in an air flow direction sandwiching a predetermined part. COPYRIGHT: (C)2009,JPO&INPIT
