PROBLEM TO BE SOLVED: To provide a fixing structure of a planting base for rooftop greening for improving wind resistance to a strong wind load of a multistory by securing a draining clearance between the planting base using ALC boards and a rooftop concrete slab, and simultaneously and surely fixing a plurality of planting bases on the rooftop concrete slab. SOLUTION: This planting base is formed by layering a plant raisable cultivating material on upper surfaces of the ALC boards, and is juxtaposed in a plurality of rows on the rooftop concrete slab. Each corner of the planting base is provided with a fixture composed of a baseplate, a vertical bolt erected from the center of the baseplate, a lower sandwiching plate having a central part threadedly engaged with the vertical bolt and an upper sandwiching plate having at the center a nut threadedly engaging with the upper end of the vertical bolt, and the planting base is sandwiched between the upper-lower sandwiching plates.
