A resistor element including a cylindrical ceramic support having two openings open on longitudinally opposite end faces thereof, an electrically resistive layer formed on an outer circumferential surface, a pair of electrical conductors for connecting the electrically resistive layer to an external circuit, each of which has an end portion inserted into a corresponding one of the openings of the ceramic support, and an electrically conductive adhesive filling each opening of the ceramic support, for securing the end portion of the corresponding conductor to the ceramic support. The electrically resistive layer has two integrally formed extensions for covering the opposite end faces of the ceramic support, respectively, and respective inner wall surfaces of the openings of the ceramic support. The conductors are electrically connected to the extensions of the resistive layer by the electrically conductive adhesive filling each opening of the ceramic support.

An electroluminescent device wherein a light-emitting layer is formed between electrode layers, and a selenium layer is formed between the light-emitting layer and at least one of the electrode layers. Each of the crystals in the selenium layer grows in a columnar shape in the direction extending at right angles to the light-emitting layer.
