PROBLEM TO BE SOLVED: To provide a termite proof and weed proof sheet suitable for outdoor use around a building, and to provide a termite proof structure of a building.SOLUTION: A termite proof and weed proof sheet 100 laid on a surface of a ground G includes an upper layer and a lower layer, the upper layer including a nonwoven fabric imparted with a shading property and a hydrophilic property and the lower layer including a nonwoven fabric imparted with a termite proof function by containing termite proof agent. The upper layer and lower layer are connected by a needle punch. The termite proof structure of a building includes: a foundation C supporting a building H and the termite proof and weed proof sheet 100 laid on a surface of the ground G on an outdoor side of the foundation C. The termite proof and weed proof sheet 100 is laid on a surface on the outdoor side of the foundation C in a predetermined range adjacently. The termite proof structure of a building further includes: a deck material 12 arranged along the surface on the outdoor side of the foundation C and plural support legs 11 arranged between the deck material 12 and ground G for supporting the deck material 12 from below. On the surface of the ground G in an area covered by the deck material 12, the termite proof and weed proof sheet 100 is laid.SELECTED DRAWING: Figure 1
