Abstract
In a bulb-form lamp, a threaded portion of a lamp cap , that is, a shell is made of a conductive resin. The conductive resin shell and an eyelet constituting the lamp cap are composite parts, which are molded integrally with a lamp case . A part of the conductive resin shell is provided with a terminal connective portion projecting into the lamp case . The terminal connective portion 30 is connected with an electrode terminal led out of a printed circuit board of a lighting circuit so that the conductive resin shell and the lighting circuit are electrically connected. By doing so, it is possible to simplify the assembly of bulb-form lamp, and to reduce an assembly cost, and further, to manufacture a bulb-form lamp having a high quality and a lamp case for the bulb-form lamp.
