The present invention relates to a nonbearing lightweight inner wall which is applied to divide an inner space of a building such as apartment houses, a high-rise residential building, and an office building. The nonbearing lightweight inner wall can simplify construction and reducing the weight as a mortar material in which an insulation material and a reinforcing metallic material are inserted is integrated. The present invention integrates a vertical stiffener (stud) and an inner filler complexly installed in a field so that the present invention simplifies the construction as a stud integration type. The present invention remarkably reduces construction costs and minimizes waste in the field. The present invention also reduces raw material costs and skilled human resources.
