PROBLEM TO BE SOLVED: To aim at suppressing leak currents between cathodes caused by evaporation of thermionic emitting material (Ba, BaO or the like) in acting at an electronic gun for a cathode-ray tube. SOLUTION: This electronic gun is comprised that a plurality of cathode main bodies KR, KG, and KB are supported by an insulation supporting body 41, and that this has a cathode structural body 42 composed that electroconductive members (49G<SB>1</SB>, 49G<SB>2</SB>) and (49R<SB>1</SB>, 49R<SB>2</SB>, 49B<SB>1</SB>, 49B<SB>2</SB>) comprised to be fixed to the insulation supporting body 41 by respectively glass-soldered from mutually opposite side faces of the insulation supporting body 41.
