Abstract

See full text

Provided is a method for manufacturing a sheet for use in a tongue plaque cleaner, capable of reliably cutting loops of thread members provided at a given density, and forming thread members each having a shape with an arc portion sufficient enough to scrape off tongue plaque, through steps that are simple, low-cost and suitable for mass production. A method for manufacturing a sheet 1 for use in a tongue plaque cleaner for scraping off tongue plaque, includes: a step of heating a sheet material having multiple looped thread members 2 protruding from one surface of the sheet material, at a temperature below the melting point of the thread members 2; and a step of forming first thread members 3, 8 and second thread members 4, 9 by cutting loops of the thread members 2 heated.
