The heat-resistant inorganic adhesive is a mixture of metal oxide powder such as alumina and an alkali metal silicate, for example, water glass, which has a slightly alkaline property of pH 8 to 9, and is hardened when it is baked by interposing both adhesive surfaces. It becomes water-insoluble and exhibits a strong adhesive force. Moreover, the cured adhesive has excellent heat resistance and can withstand the high temperature of the halogen bulb, and will not peel off even after long-term use.

(Problems to be solved by the invention) When a dichroic reflection film is formed on the inner surface of a glass reflector, a part of the reflection film substance wraps around the inner surface of the cylindrical die part, resulting in a film with a thickness of several thousand Å. May be formed. When a light bulb is adhered on such a reflective material coating,
If the adhesive strength is inferior and severe, the bulb may fall off due to the pressure when the terminal of the bulb is inserted into the socket.

Therefore, conventionally, the inner surface of the base portion is polished to remove the adhered reflective film substance, and then the light bulb is adhered. However, since the adhered film of the reflective film substance is very thin, it is difficult to visually determine the presence or absence of the film.
I was spending a lot of effort. Further, depending on the coating substance, there is a means for limiting the range of film formation by masking or the like, but there is a problem that labor is required for film formation.
