Further, an oral adhesive sheet comprising a separator release-treated on one or both surfaces thereof and a plurality of sections for application to oral mucous membrane mounted on at least one surface of the separator in a specified 2 to 5 by 2 to 5 arrangement with a specified proportion of a minimum inner diameter, Dp, of an incircle passing a center of gravity, W, of a section to a shortest distance, Di, of an adjacent section is 1.5 to 6. The substrate is preferably cloth such as non-woven fabric. Sections containing a local anesthetic can be used in surface anesthesia in dentistry.
