摘要： PROBLEM TO BE SOLVED: To hold both parts of an insulating body and an electroconductive body in common and to improve impact resistance by a material wherein in constitutional layers respectively comprising a uniform mixture of electroconductive and insulating inorg. ingredients, the concn. of the electroconductive ingredient is stepwisely changed and the interface between mutually adjoining constitutional layers is inclined to a face at right angles to the axial direction. SOLUTION: This inclined functional material M is a cylindrical rod-like one constituted of a number of constitutional layers laminated in the up and down direction and the lowermost layer L1 is an insulating body layer with 0 vol.% concn. of an electroconductive inorg. substance ingredient and 10 vol.% silica. On the other hand, the uppermost layer L8 is an electroconductive body layer with e.g. 80 vol.% concn. of an electroconductive inorg. substance ingredient consisting of e.g. molybdenum and 20 vol.% silica. In addition, in the successive constitutional layer from the lowermost layer L1 to the uppermost layer L8, the concn. of the electroconductive inorg. substance ingredient increases stepwisely from the bottom to the top. Interfaces between each of partial or the whole constitutional layers among the whole constitutional layers and a constitutional layer adjoining this is formed in such a way that the direction is inclined from a face at right angles to the axial direction.

摘要： PROBLEM TO BE SOLVED: To provide an electricity introducing material for a bulb which combines a functionally gradient material, such as being easily fused with a block tube as a block unit for the bulb, without deformation of the functionally gradient material bending or the like, when it is used with L/D exceeding 2 as the electricity introducing material, with an electrode stem. SOLUTION: A plurality of uniform composition layers, with volumetric ratio (%) of silica in a functionally gradient materials n1, n2, n3,...,nx (n1>n2>n3>...>nx), are successively layered in columnar shape, so that a columnar functionally gradient material with tilted composition continued to silica from an electrical conductor is used, when assuming D for diameter of the columnar functionally gradient material and L for a total of layer thickness of the uniform composition layer with a volumetric ratio of silica exceeding 8%, in an electricity introducing material for a bulb of L/D 2 or more, from an n1 layer side surface to the uniform layer with a volumetric ratio of silica at least 80% or less, an electrode stem is shrinkingly fitted, and an electricity introduction material for a bulb is obtained.
