Abstract
In a floor panel (10) including a foamed cement board (1) having at least a foamed cement layer (3), a top plate (5a) attached to an upper surface of the foamed cement board (1), and a bottom plate (5b) attached to a lower surface of the foamed cement board (1). The foamed cement layer (3) is configured so that the layer (3) has a porous hardened cement phase and a fiber dispersed in the phase. Also, the layer (3) has a thickness within a range from 12 to 30 mm and a specific gravity within a range from 0.8 to 1.5. Thereby, the floor panel can be light in weight while desired strengths for the floor panel are established. The floor panel can be readily produced without any complicated processes.

A floor panel comprising:
- a foamed cement board comprising at least a foamed cement layer;
- a top plate attached to an upper surface of the foamed cement board;
- and
- a bottom plate attached to a lower surface of the foamed cement board,
- wherein the foamed cement layer comprises a porous hardened cement phase and a fiber dispersed in the phase, and the foamed cement layer has a thickness within a range from 12 to 30 mm and a specific gravity within a range from 0.8 to 1.5,
- at least one of the top and bottom plates is a metal plate,
- a marginal part of the top plate and a marginal part of the bottom plate cover at least a part of a peripheral surface of the foamed cement board,
- wherein the marginal part of the top plate and the marginal part of the bottom plate are opposed to each other along the peripheral surface of the foamed cement board, and
- opposing surfaces of the marginal part of the top plate and the marginal part of the bottom plate are separated by a distance (d).
