TOOL FOR REPELLING INJURIOUS BIRD

摘要

PROBLEM TO BE SOLVED: To provide a tool for repelling injurious birds in which injurious bird-repelling effect is maintained for a long term in spite of a simple structure. SOLUTION: This tool features being formed of the following substrate material and a reinforcing board 5 superimposed on the side of a reflection coating 2 of the substrate material: the surface of the resin substrate board 1 has minute pattern where many grooves having a depth of 0.05-1 mm, many lines of concavity having a depth of 0.1-1.3μm or many lines of convexity having a height of 0.1-1.3μm are arranged, the reflection coating 2 is formed on the minute pattern and the substrate material has >=70% reflectivity for incidence light from the side of the transparent resin substrate board 1. The resin substrate board 1 may be colored orange so as to have a characteristic absorption of 550-770 nm.
