ABSTRACT:
The present invention relates to a manufacturing method of obtaining a photoelectric converting device which can sufficiently maintain airtightness of a housing space for photocathode without degradation of the characteristics of the photocathode. In accordance with the manufacturing method, on the side wall end face of a lower frame and a bonding portion of an upper frame forming an envelope of the photoelectric converting device, a multilayered metal film of chromium and nickel is formed. In a vacuum space decompressed to a predetermined degree of vacuum and having a temperature not more than the melting point of indium, these upper and lower frames introduced therein are brought into close contact with each other with a predetermined pressure while sandwiching indium wire members, and accordingly, an envelope having a housing space whose airtightness is sufficiently maintained is obtained.
