PROBLEM TO BE SOLVED: To provide an optical scanning apparatus which realizes simplified configuration and reduction of the dimensions including the diameter.SOLUTION: The optical scanning apparatus comprises: an optical fiber; a drive part for causing an emission end part of the optical fiber to vibrate; a current detection part for detecting an electric current flowing through the drive part; and a control part for controlling the drive part on the basis of an output of the current detection part and causing light emitted from the optical fiber to perform scanning. The drive part has a plurality of vibration element parts 28a-28d, which have their respective grounding ends commonly connected in the drive part. The current detection part 55 detects an electric current at power supply ends of the plurality of vibration element parts 28a-28d. |
