A cross-laminated timber panel comprises a plurality of layers of lumber boards, each layer comprising a number of the lumber boards laid side-to-side pointing to a direction, each layer being disposed perpendicular to the direction of an adjoining layer; and an insert member replacing one of the lumber boards, the insert member having a different material or configuration than the lumber boards.

To provide a means for efficiently reinforcing strength around a through hole of a CLT panel. A CLT panel reinforcing structure includes a CLT panel having a through hole; hole; a first reinforcing member having a first plate and a first pipe, the first plate having a first opening; and a second reinforcing member having a second plate and a second pipe, the second plate having a second opening. In the first reinforcing member, the first pipe is inserted into the through hole in a state where an outer peripheral surface of the first pipe abuts on an inner peripheral surface of the through hole, and a largest surface of the first plate abuts on a first surface of the CLT panel. In the second reinforcing member, the second pipe is inserted into the through hole in a state where an outer peripheral surface of the second pipe abuts on an inner peripheral surface of the first pipe, and a largest surface of the second plate abuts on a second surface located opposite to the first surface of the CLT panel.
