PROBLEM TO BE SOLVED: To obtain an accurate interval (Q size) between a perforated shadow mask face and the inner face of a panel section faceplate arranged to face it by directly measuring the Q size, and adjusting the Q size based on the measured result. SOLUTION: A shadow mask assembly 2 is fitted in a panel section 1 through a first process that the perforated shadow mask face 3U of the shadow mask assembly 2 held by a position adjusting mechanism 5 is arranged to face a faceplate 1F in a fixed panel section 1, a second process that the interval (Q size) between the perforated shadow mask face 3U and the inner face of the faceplate 1F arranged to face it is directly measured by a distance measuring instrument, a third process that the position adjusting mechanism 5 is finely adjusted based on the measured result in the second process, and a fourth process that locking springs are fitted between support pins 7 protruded in the panel section 1 and the support frame 4 of the shadow mask assembly 2.
