There are provided an ion generating unit and a lighting apparatus that are capable of quickly raising an ion concentration to a predetermined concentration upon start-up and elongating a product life while maintaining the predetermined ion concentration. In the ion generating unit configured to control driving of an ion generating element A 31 and an ion generating element B 32 for generating ions by a controller 52, the controller 52 drives the ion generating element A 31 and the ion generating element B 32 upon start up, and is configured to keep driving for a predetermined time period T1; thereby, the ion concentration of a space upon start up can quickly be raised to the predetermined concentration. Further, the controller 52 is configured to drive the ion generating element A 31 and the ion generating element B 32 intermittently and one after another in order after the predetermined time period T1 has elapsed; the product life can be elongated while maintaining the predetermined ion concentration and shortening the driving time of the ion generating element A 31 and the ion generating element B 32. |
