A cathode ray tube includes a panel, a funnel and a funnel yoke portion having a non-circular-shaped vertical section. When a diagonal portion thickness on a certain vertical section between a reference line and a neck line is Td and a long side portion thickness at the same vertical section is Th, a glass structure of a cathode ray tube satisfies 0.5&#x3c;Th/Td&#x3c;1.01. When a diagonal portion thickness at a top round is Dt', a long side portion thickness is D&#x2032;, a short side portion thickness is D&#x2032;, a diagonal portion thickness at a reference line is Dt, a long side portion thickness is D, and a short side portion thickness is D, then the glass structure of a cathode ray tube satisfies 1.3&#x2266;Dt&#x2032;/Dt&#x3c;1.80.
