Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a floor base material which can reduce the propagation of an airborne sound and/or a solid borne sound of lightweight floor impact to a lower floor, which is generated at an upper floor of an architectural structure.SOLUTION: In a floor base material 100, a projection 210 of a resin projection sheet layer 200 and a second cushion layer 320 in a cushion layer 300 come in contact with each other, and except the contacting position, a space region AR 30 is provided between the resin projection sheet layer 200 and the cushion layer 300. A flooring material 500 is formed by sequentially stacking a flooring board 510 and the floor base material 100.
