PURPOSE: To provide an incandescent lamp wherein a pigment layer is provided at a part or the entire part of the inner surfac of a light permeating housing, and a light diffusing fine powder is electrostatically laminated and coated on the pigment layer, thereby to prevent the pigment layer from falling off and impart vivid color tone and an anti-dazzlement effect.
