る。2. Description of the Related Art As one of the air cleaners for removing cigarette smoke and offensive odors generated in offices, restaurants, amusement facilities, etc., one using an electric dust collector is disclosed in, for example, Registered Utility Model No. 3033859. In this configuration, the number of discharges per unit area is large, and the purification efficiency is excellent. On the other hand, in the above configuration, as shown in FIG. 6 of the publication, the needle electrode is formed by integrally bending the bent electrode plate members 30 and 31 on the connection support member 19 obtained by bending the stainless plate. A pin member serving as a discharge electrode is fitted into the pin mounting holes ha and hb of the bent electrode plate member by a hammering machine such as an air hammer. In this case, if a large number of needle electrodes are provided, the total weight thereof becomes heavy because the supporting member is made of stainless steel, and the dust collecting unit is detached from the air cleaner main body when cleaning the dust collecting unit. In this case, there is a problem that the work requires labor.
