A lightweight panel and a noise-proof floor structure using the same are provided to prevent noise between the stories of a building by installing a plurality of lightweight panels on a slave and forming a gap at the connection of the lightweight panel as a noise absorbing path. A lightweight panel comprises a shock absorbing layer(11), a lightweight concrete layer(12), and a non-asbestos cement board(13). The shock absorbing layer is made of foam polystyrene. The concrete is mixed with the foam polystyrene of 150~180, fluidization solution of 1~3, water of 40~50 for 100 parts by weight of the cement. The mixed concrete is poured on the lightweight concrete layer. The non-asbestos cement board has sound-proof function. The shock absorbing layer, the lightweight concrete layer and the non-asbestos cement board are consecutively stacked.
