Abstract
A filament lamp in which the article to be treated can be uniformly heated, and in which the disadvantage of poor sealing or the like does not arise even in the case of inserting a host of metal foils into a hermetically sealed portion is achieved in a filament lamp in the bulb of which there are several filament bodies, in which filaments and leads for supply of power to the filaments are connected to one another, and in which, on an end of the bulb, there is a hermetically sealed portion in which there is a rod-shaped sealing insulator on the periphery of which several electrically conductive components that are connected to the filaments are arranged spaced from one another.
