PROBLEM TO BE SOLVED: To provide an optical mouse-corresponding mat which achieves excellent response (operation performance) of an optical mouse and high transparency and which is made of an olefin resin.SOLUTION: An optical mouse-corresponding mat is formed by superposing a top layer made of a nylon resin or polybutylene terephthalate on a base material layer made of an ethylene-based copolymer resin via an adhesion layer made of an olefin resin obtained by graft-polymerizing maleic anhydride. The adhesion layer and/or the top layer contain 0.05-0.50 pt.wt. of aluminum powder whose weight average particle size is 5-50 μm relative to 100 pts.wt. of the resin forming each layer. |
