The face material 2 is provided with: a sheet material 5 having a bendable bending part 9 and a break-open part 10 for forming an opening when bent at the bending part 9; a sealing material 6 for sealing the break-open part 10 by being adhered to the break-open part 10 and the surround parts thereof on the sheet material 5; and a cover material 7 for covering the sealing material 6. The cover material 7 is adhered so as to cover the bending part 9 except where a covering part 11 of the sealing material 6 covers the break-open part 10. An adhesion-prevention part 12 for reducing the adhesion area or for preventing the covering part 11 from being adhered to the cover material 7 and/or the sheet material 5 is formed above and/or below the covering part 11 of the sealing material 6.
