PROBLEM TO BE SOLVED: To provide a floor material capable of preventing an omission of nailing for a male tongue section.SOLUTION: A floor material 1, which includes male and female tongue sections 10 and 20, is configured to be fixed to a sub-floor by driving a nail 3 from the side of a top surface 10a of the male tongue section 10. The top surface 10a of the male tongue section 10 assumes an approximately flat shape. A protrusion 11A inhibiting fitting in the fitting of the female tongue section 20 is formed on the top surface 10a. When the nail 3 is driven into the upper portion of the protrusion 11A from above, the protrusion 11A is pressed by a head 3a of the nail 3 and changed not to inhibit the fitting. |
