PROBLEM TO BE SOLVED: To provide a protection lattice excellent in protectiveness, burglar- proof performance, especially cutter-proof performance in comparison with the conventional protection lattice and, at the same time rationalizing and simplifying a construction form of the protection lattice even if the protection lattice is mounted by the simplified and rationalized construction form. SOLUTION: When a wall hole H<SB>w</SB>is formed in a wall of a building or the like on which the protection lattice is mounted by casting concrete, the inner circumferential surface of the wall hole H<SB>w</SB>is formed in a recessed groove shape G, and a metal-made frame body 1f having a size to be stored in the wall hole H<SB>w</SB>includes a lattice batten 1g of a bar material such as a metal bar or the like inside thereof, the lattice body 1 erecting a plurality of bolts 2 projected toward the outer circumferential surface to the inner circumferential surface of each side of the frame body 1f is provided to the recessed groove section of the window hole H<SB>w</SB>, the concrete C is cast in the recessed groove section G in a state to screw until each bolt 2 is abutted on the bottom of the recessed groove section G.
