A high-strength wire mesh comprising a wire having a tensile strength exceeding 2200 MPa, wherein 50 m or greater of said wire is used to knit 1 m2 of the wire mesh.

A high-strength wire mesh comprising a wire having a tensile strength exceeding 2200 MPa, and having an amount of deflection of 707 mm or greater as a net body under following conditions, wherein:

• 50 m or greater of said wire is used to knit 1 m2 of the wire mesh, and wherein
• a length of a cantilever beam that supports said net body in a line wire direction in a cantilevered state is 1000 mm, and an amount of displacement in a vertical direction of a free end at this situation is defined as the amount of deflection.

A high-strength wire mesh comprising a wire having a tensile strength exceeding 2200 MPa, wherein:

• the wire mesh is a rhombus wire mesh, and
• an annular portion having a length of one round or greater of a helix is formed at an end portion of a line wire constituting the rhombus wire mesh and formed in a helical shape.

A high-strength wire mesh comprising a wire having a tensile strength exceeding 2200 MPa, and having an amount of deflection of 707 mm or greater as a net body under following conditions, wherein:

• a basic aspect of the wire mesh is a rhombus wire mesh, and
• the wire mesh has a thickness of 30 mm to 70 mm by forming a line wire constituting said rhombus wire mesh in a helical shape having a thickness, and wherein
• a length of a cantilever beam that supports said net body in a line wire direction in a cantilevered state is 1000 mm, and an amount of displacement in a vertical direction of a free end at this situation is defined as the amount of deflection.
