The purpose of the present invention is to provide an optical component driving device and the like that detect with high sensitivity the displacement of an optical component in order to control with high accuracy the position of the optical component. To achieve this purpose, this representative optical component driving device is provided with the following: an optical component; a holder to which the optical component is attached; a support member that is connected to a fixed member and that displaceably supports the holder with respect to the fixed member; a reflection member that is provided to a portion of the support member and that has a surface which is roughly orthogonal to the displacement direction of the holder; a light emitting element that projects light towards the reflection member; and a light receiving element that receives reflected light reflected by the reflection member. |
