Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a color picture tube and its manufacturing method wherein a shape as a whole set is made down-sized as much as possible even if an image plane itself has become larger when it is assumed that the whole set becomes large-sized because mounting fittings for the color picture tube to be mounted in a case body also become larger, accompanied with a large-sizing and flattening of the color picture tube. SOLUTION: By the mounting fittings 21 of the color picture tube 22 being positioned in the inside of a block sectioned by a tangential extension lines of respective sides of a face panel 11, a spatial distance between the color picture tube 22 and the case body 31 is made as small as possible. As a means for this, when a mounting fittings 21 is formed, a lug piece 38 and a stationary piece 40 are press-molded in a nearly right angle, and a through-hole 39 is drill-installed and formed in the lug piece 38 afterwards.
