PROBLEM TO BE SOLVED: To provide a new floor heat insulating panel and laying structure of the floor heat insulating panel that can improve airtightness, fix a column onto a sill without forming a cutout at a corner part or an end part and easily realize a barrier-free state, eliminating step difference even in the case a Western-style room and a Japanese-style room adjoin with a doorsill in between. SOLUTION: This floor heat insulating panel comprises a floor board 2 formed in square shape; four frame plates 3-6 with the upper ends fixed to both ends and both sides of the floor board 2; a plurality of partition plates 7-11 fixed in parallel to partition the lower face of the floor board 2 formed of four frame plates 3-6; heat insulating materials 12-17 fitted into spaces formed by the partition plates 7-11 and frame plates 3-6; plastic airtight materials 18 formed at the outer side faces of four frame plates 3-6 and brought into pressure contact with the side face of the sill 21.
