PROBLEM TO BE SOLVED: To inexpensively provide a light-weight steel partition wall which has a sound insulation performance capable of preventing squeak noise (rubbing noise) from occurring over a long period and a fire-resistant performance. SOLUTION: This light-weight steel partition wall includes an upper runner 2, a lower runner 3, studs 4 the upper and lower ends of which are inserted in the upper and lower runners, gypsum boards 5 affixed to the studs, and glass wool 6 filled in the hollow parts of the gypsum boards. The studs and the upper runner are displaced relative to each other in the in-plane direction to absorb the inter-layer displacement of a building. Back batten plates 7 are interposed staggered between the studs and the gypsum boards. The upper runner uses one the lateral width B of which is larger than the lateral width A of the studs and smaller than the sum of the lateral width A of the studs and the thicknesses C, C of the back batten plates which are disposed on both sides of the studs. An elastic cushioning material 8 joined to the studs is interposed between the upper end both side surfaces of the studs and the inner surface of the upper runner at a position higher than the upper end of the back batten plates to thereby form the gap b between the gypsum boards and the outer surface of the upper runner.
