Abstract
Abstract An LED array head has an LED array which selectively emits light. The LED array is mounted on a substrate in a flip chip form with a light emitting section located opposed to a surface of the substrate. A fiber bundle including a plurality of optical fibers is buried in the substrate with an end portion of the fiber bundle located at a position in the vicinity of the light emitting section of the LED array.
