An exhaust gas treatment device (101,102) includes an electrode assembly (1). The electrode assembly (1) has an ion-conducting layer (3), anode (4) and cathode (5) electrodes, and a filter (6). The anode (4) and cathode (5) electrodes are provided spaced apart from each other on the ion-conducting layer (3) having proton conductivity. The filter (6) is provided between the anode (4) and cathode (5) electrodes and the thickness of the filter (6) is greater than that of the anode and cathode electrodes for capturing particulate matter in exhaust gas. One part of the electrode assembly is overlapped with different part thereof in such a way that the filter (6) of the one part thereof supports the different part thereof so that a space is formed between the two parts thereof. The anode (4) and cathode (5) electrodes and the filter (6) are arranged such that exhaust gas supplied to the electrode assembly contacts with the anode electrode (4), and flows through the filter and contacts with the cathode electrode (5).
