PROBLEM TO BE SOLVED: To provide a stairs capable of facilitating the positioning of an upper step and being constructed in a short period of time by being formed so as not to project a supporting member or the like from the edge inside a step forming the stair. SOLUTION: A step body 1 is constituted by having a plurality of slots 11 and 12 penetrated in parallel while having a predetermined interval, and a supporting section 1 is so constituted that plate-like connecting sections 3 and 4 are provided on the surface of the step body in parallel. A plurality of through-holes 31 and 41 having the approximately same intervals as those of the slots of the step body are formed in to the connecting sections. When connecting members 51 and 61 are inserted into the through-holes, the connecting members can be simultaneously inserted into arbitrary positions of the slots. The supporting section is constituted of a body supporting section 121 and a connecting supporting section 122, and it is so constituted that heights of connecting sections 103 and 104 can be changed by the attachment state of both of them.
