the other connecting surface facing the end surface is flat;
An electron tube characterized in that the outer circumference of the envelope has a width greater than 0.4 mm. 2. The electron tube portion is formed of a window portion and a cylindrical envelope portion, a metal ring is coupled to both the window portion and the cylindrical envelope portion, and their end surfaces form a bonding surface. 2. The electron tube according to claim 1, wherein opposing end surfaces of metal rings are joined to each other by a press seal, and the metal ring having a narrow joining surface is provided in a window portion. 3. A metal ring whose bonding surface has a width in the range of 0.1 mm to 0.4 mm is bonded to the cylindrical envelope portion;
3. The electron tube according to claim 1, wherein the opposing bonding surfaces of the window portion are constructed of a metal layer provided on the window portion. 4. Any one of claims 1 to 3, characterized in that the metal ring having a joint surface with a width in the range of 0.1 mm to 0.4 mm has a circular, elliptical or polygonal cross-sectional shape.
