The casing core material is disposed at the end edge part on the opening part 7 side in both front and back surfaces of a wall 6 so that an engaging part is disposed on the opposite side to the opening part of the wall, and the end face on the opposite side to the engaging part is disposed flush with the end face facing the opening part of the wall. The decorative laminated sheet cover frame involves the end part on the opening part side of the wall from the casing core material with one end part 3a engaged with the engaging part of the casing core material.
