Abstract
PURPOSE:To facilitate indication of the properties of small parts, by a method wherein a polarity identification mark which has a discontinuity and indicates polarity and grade of the parts is provided along the circumference of the sealing portion and sub-mark which indicates the grade of the parts by numbers, etc. is provided on the discontinuity. CONSTITUTION:A polarity identification mark (cathode line) 3 with a discontinuity region 6 is provided along the circumference of the sealed portion of a DHD element which consists of lead wires 2 and the sealed portion 1. A grade indication sub mark 7 which consists of numbers or letters is provided on the discontinuity region 6. With above method, as the marks 3 and 7 can be coded by various colors, many grades of the products can be identified by the combination of colors and the types of letters. Thus, indication of the properties of smaller electronic parts is facilitated.
