Claims

[Scope of utility model registration request]

It has a flat tubular body formed by joining and combining a panel and a funnel, and a terminal for supplying signals into the flat tubular body is led out from a joint between the panel and the funnel in a gradually narrowing part of the funnel. 1. A flat cathode ray tube, characterized in that the width of the seal end face at the gradually narrowing portion of the funnel is made wider than the width of the seal end face at other portions.
