PURPOSE: To improve economy and execution in fixing a face member to a frame member with certainty, without exposing a nail head onto the surface of the face member.

CONSTITUTION: In a face member fixing structure for fixing a face member 12 to the surface of a frame member 11, a flat nail 20 is adopted, which nail 20 has a flat nailing part having a large surface area continued from a head 21. The flat nail 20 is obliquely nailed from a rear surface of the frame member 11 into the face member 12. A normal nail 30 is nailed from a rear surface of the frame member 11, for penetrating into the nailing part 22 of the flat nail 20.
