Abstract
A UV light sensing element has at least a first electrode and a sensor. The first electrode has a semiconductor containing at least one element selected from Al, Ga and In together with nitrogen or oxygen, and the sensor layer has a semiconductor containing at least one element selected from Al, Ga and In together with nitrogen. A longer wavelength end of an absorption spectrum for the first electrode is located at a position nearer to a shorter wavelength side than a longer wavelength end of an absorption spectrum for the sensor.
