Abstract: A dust collection sheet includes: a first electrode extending in a first direction from an upper stream of an air flow path toward a lower stream of the air flow path, the first electrode including a first electrode layer to which a first voltage is applied and a first dielectric layer covering the first electrode layer; a second electrode disposed in a second direction orthogonal to the first direction, the second electrode including a second electrode layer to which a second voltage is applied and a second dielectric layer covering the second electrode layer, wherein the second voltage is different from the first voltage; and a third electrode disposed parallel to the second electrode in the first direction, the third electrode including a third electrode layer to which a third voltage is applied and a third dielectric layer covering the third electrode layer, wherein the third voltage is different from the second voltage, wherein the second electrode further includes a discharge portion, the discharge portion including a portion of the second electrode layer that is not covered by the second dielectric layer, and the third electrode includes a corresponding portion facing the discharge portion, the corresponding portion including a portion of the third electrode layer that is not covered by the third dielectric layer, wherein the corresponding portion is configured to cause a charging action to occur with the discharge portion.
