The present invention provides an ion generation device wherein, in a case where an abnormality has occurred in the device, the abnormality and the location of the abnormality can be identified easily. PCI control circuits (51-54) determine whether or not the operation of the ion generation device is normal. A microcomputer (50) controls a louver control circuit (58) such that the open/close states of louvers (21-24) differ for cases where it has been determined by the PCI control circuits (51-54) that ion generation units (41-44) are normal and where it has been determined that the ion generation unit(s) is/are not normal. For example, in a case where it has been determined by the PCI control circuits (51-54) that the discharge of ions from one of a plurality of discharge ports (11-14) is not normal, the operation of the ion generation device (100) is stopped and only the louver corresponding to said discharge port is opened.
