PROBLEM TO BE SOLVED: To enable easy removing of a matching oil left over on a measurement surface composed of a glass for an optical measuring apparatus. SOLUTION: The cleaning sheet 101 is constructed of a support base material 102 with flexibility and a resin layer 103 which is formed on one side surface of the support base material 102 and adsorbs the matching oil. The support base material 102 is preferably, for example, a plastic film of polyester, polyethylene, polypropylene or polyethylene terephthalate, or paper, etc. The resin layer 103 is adhesive enough to stick to the support base material 102, and also, is composed of a resin with lipophilic nature. Further, the resin layer 103 is acceptably made up of, for example, an acrylic adhesive which is obtained by copolymerizing not less than two different acrylates with different main chain lengths, with an isocyanate-based or an epoxy-based crosslinking agent.
