    Abstract: A greensheet comprising an inorganic pigment and an inorganic matrix component is applied to a surface of a glass substrate and fired for fixing. The formed shading film has a portion whose thickness is 90% or more of the maximum thickness of the shading film within the range of 0.5 mm from an edge of the shading film. Thus, a shading film that has distinct end faces and has an excellent thickness uniformity can be formed with a good positional accuracy. Therefore, a lamp having a highly precise light distribution property can be obtained. In addition, a lamp having such a property can be obtained with a few steps and at a low cost.
