PROBLEM TO BE SOLVED: To provide a collection net with high efficiency of collection of airborne dust.SOLUTION: A collection net includes a net base material 1, and an adhesive 2 which is applied to the net base material 1. The net base material 1 includes a plurality of longitudinal net legs 11 which are formed by passing through adjacent loops to longitudinally connect the loops to each other and which are longitudinally elongated almost in parallel with one another, and a plurality of lateral net legs 12 which are laterally elongated to connect a section between the adjacent longitudinal net legs 11. A quadrangular mesh 10 is formed between the pair of longitudinal net legs 11 and the pair of lateral net legs 12. Two or more pieces of insertion weft 13 are laterally elongated in each mesh 10. The two or more pieces of insertion weft 13 are arranged at almost regular intervals between the longitudinal net legs 11 facing each other with the mesh 10 in between so as to separate the meshes 10 into approximately rectangular space parts 100 at almost regular intervals. The apparent diameter of the insertion weft 13 is smaller than the apparent diameter of the longitudinal and lateral net legs 11 and 12. |
