Two panel frame members having a rear seal member and at least facing each other have a fixing tool insertion hole at a position facing the front wall of the outer frame material, and the panel body fixing tool includes a fixing tool and an auxiliary material, The auxiliary material has a fixing tool insertion hole opposite to the fixing tool insertion hole of the panel frame material, and is fixed to the expected surface of the boundary wall. Is inserted from the rear side into the insertion hole of the panel body and the insertion hole of the auxiliary material to fix the panel body to the auxiliary material, and there is a space between the outer frame and the panel body, and the auxiliary material and the panel frame One insertion hole of the material has a larger diameter than the other insertion hole, and the position of the fixing tool can be adjusted up, down, left and right, and the panel body fixing tool is shielded by the front seal member and the rear seal member. A wall surface structure characterized by that.
