Abstract
The object is to provide a photoelectric surface member which allows higher quantum efficiency. In order to achieve this object, a photoelectric surface memberis a crystalline layer formed by a nitride type semiconductor material, and comprises a nitride semiconductor crystal layerwhere the direction from the first surfaceto the second surfaceis the negative c polar direction of the crystal, an adhesive layerformed along the first surfaceof the nitride semiconductor crystal layer, and a glass substratewhich is adhesively fixed to the adhesive layersuch that the adhesive layeris located between the glass substrateand the nitride semiconductor crystal layer
