PROBLEM TO BE SOLVED: To prevent a defect in a mesh part by forming a thin part on the boundary between a woof part and a warp part which constitute the mesh part and a frame body and making the thickness of the thin part in the thickness direction smaller than that of the mesh part in a synthetic resin net body in which the frame body is molded constantly around the mesh part. SOLUTION: In a mesh body 1, a frame body 3 is molded integrally around a mesh part 2, and a thin part 4 is formed on the boundary between the mesh part 2 and the frame body 3. In the mesh part 2, a woof part 2a and a warp part 2b, which are formed to have a square cross section, meet at right angles, and each end part is joined to the thin part 4. The thickness of the thin part 4 in the thickness direction is made smaller than that of the mesh part 2. An induction part 2c for reinforcement and for smooth entry of a synthetic resin is formed in the mesh part 2. The thin part 4 is formed in a plate shape and joined to the periphery of the mesh part 2, and the frame body 3 is joined to the outside periphery of the thin part 4. The frame body 3 has a square cross section and is joined to the outside periphery of the thin part 4, thick, and formed to secure the strength of the whole net body 1. |
