Further, the upper end fixing member 24 has a dimension along the panel thickness direction that is substantially the same as the thickness dimension of the panel body 10. With such a configuration, as shown in FIGS. 1A and 2A, when the panel body 10 is arranged along the longitudinal direction of the field edge 3 in the width direction, the panel body 10 is arranged. The side ends of the ceiling panels 4 and 4 on both sides in the thickness direction of 10 can be stably fixed to the field edges 3 and 3 on both sides. That is, by arranging the field edges 3 and 3 on both sides in the panel thickness direction so as to sandwich the upper end fixing member 24 arranged on the upper side of the panel body 10, the thickness of the panel body 10 is formed on these field edges 3 and 3. The side ends of the ceiling panels 4 and 4 on both sides in the longitudinal direction can be fixed. Further, as shown in FIGS. 1 (b) and 2 (b), when the panel body 10 is arranged so that the width direction is orthogonal to the longitudinal direction of the field edge 3, both sides of the panel body 10 in the thickness direction are arranged. The side end faces of the ceiling panels 4 and 4 can be stably abutted on both sides of the panel body 10 in the thickness direction. That is, even when there is a gap between the upper end surface 10a of the panel body 10 and the field edge 3, the lower surface 24a of the upper end fixing member 24 is brought into contact with the upper end surface 10a of the panel body 10 to bring the ceiling panels on both sides into contact with each other.

With such a configuration, it is possible to suppress the interference of the upper end fixing member 24 with the members and devices arranged on the upper side of the field edge 3.

The upper end fixing member 24 may be formed of a metal-based material or a synthetic resin-based material, but in the case of a block shape, the upper end fixing member 24 is formed of a wood-based material from the viewpoint of the fixing property of the fixing tool 30 or the like. It may be the one that has been done.
Further, the upper end fixing member 24 may be arranged at a pitch similar to the pitch on which the field edge 3 is provided (for example, about 300 mm to 500 mm) at intervals along the panel width direction. In this case, when fixing the panel body 10 whose width dimension is smaller than the pitch, it may be fixed to one upper end fixing member 24. Note that FIGS. 2A and 2B show an example in which the pitch between the upper end fixing members 24, 24 adjacent to each other in the panel width direction is relatively small, but the present invention is not limited to this mode.
