To surely manage ALC panels by an IC tag by eliminating the risk of separation of the IC tag from the ALC panel and securing a required reading distance of the IC tag by preventing an effect of steel members.
In the ALC panel 1, a steel cage 2 and the IC tag 10 with the end of an outer antenna 12 separated from a nearest steel reinforcement member 3 by at least 3 mm, are embedded in an ALC base material 7 before autoclave curing. When using a tape type IC tag 10, the length direction of the IC tag may be disposed parallel or tiltedly to the length direction of the nearest steel reinforcement member. The IC tag is preferably separated from the nearest steel reinforcement member 3 in the vertical direction for keeping a vertical separating distance of the end of the outer antenna from the nearest steel reinforcement member. The IC tag is preferably attached to the steel reinforcement member 3 via an attachment member.
