PROBLEM TO BE SOLVED: To provide a system floor structure and an underfloor wiring duct used therefor, capable of perfect underfloor wiring, superior in thermal insulation performance and soundproof performance, usable in common to floor heating, extremely easy in laying work, and inexpensive in laying cost. SOLUTION: This system floor structure is formed by laying a floorboard P on an interval forming means DM having the predetermined thickness for forming an underfloor wiring space S interposed on a base floor surface BF such as a floor slab. The system floor structure is characterized in that an underfloor wiring line is formed by arranging the underfloor wiring duct 1 having a wiring storage groove 2 for storing underfloor wiring Wi in a straight line shape or a square shape between the base floor surface and the floorboard, and the underfloor wiring duct forms the interval forming means.
