A device for detecting direction, height and intensity of a light which facilitates detection and provides high accuracy. The device includes a glass substrate, on which a resistant layer for detecting the X coordinate position, a photoconductive layer utilizing the photoconducting effect of a photoelectric converting layer, and a resistant layer of metallic electrode resistor body for detecting the Y coordinate position, laminated in order. The resistant layers are provided respective two lead electrodes X, X' and Y, Y'. By applying 5V and 0V, for example, to X and X', a voltage Vx corresponding to the position where the light is irradiated can be directly obtained through Y or Y'. Namely, the X coordinate position of the point where the light passes can be easily and accurately detected. By applying +5V and 0V for Y and Y', Y coordinate of the light irradiated point can be obtained, and by applying the same potential to X and X', light intensity can be obtained.
