PROBLEM TO BE SOLVED: To provide a dust collecting device which is compact and has a large dust collection area. SOLUTION: The protruded part (42) of a first electrode (40) is formed into the shape of a lengthy plate that is extended so that it may straddle a plurality of lattice holes (46) of the first electrode (40). The lattice holes (56) of a second electrode (50) are formed into the shape of a lengthy hole that is extended so that they may be opposite to the protruded part (42) of the first electrode (40). The protruded part (42) of the second electrode (50) is installed in parallel to the lengthy direction so that it may be opposite to the lattice holes (46) of the first electrode (40) at the marginal part (54a) of the lengthy arm side of each lattice hole (56) of the second electrode (50).
