The present invention relates to a flooring material and a fabrication method thereof. Since the invention forms the flooring material using bio-degradable resin which can be fabricated with materials extracted from the reproducible resources, the invention solves the supply and demand problem of raw materials caused by the depletion of oil resources. Further, the invention improves the production efficiency of the flooring materials by applying a calendaring method during the fabrication process, emits few environmentally-harmful materials including CO.sub.2 or the like, and provides the environmentally-friendly flooring material which is discarded easily. In addition, the invention can solve the problem caused by the size change which occurs when a bio-degradable sheet is used, whereby a stably and continuously-usable flooring material is provided.

This application provides a housing structure, a production method thereof, and an electronic device. The housing structure includes an appearance effect layer, a metal layer, a connection layer, and a non-metal layer that are laminated. The connection layer is configured to bind the metal layer and the non-metal layer. The appearance effect layer is formed after surface processing is performed on the metal layer. The housing structure includes both the metal layer and the non-metal layer. The metal layer and the non-metal layer are bound by using the connection layer, so that the housing structure has advantages of a metal layer housing and a non-metal layer housing. In addition, the appearance effect layer formed after surface processing is performed on the metal layer can ensure that the housing structure has a metallic appearance with an aesthetic appeal.
