description The invention relates to a continuous casting and hot rolling shaping method for a porous metal sheet. The method includes extruding a molten metal through a nozzle with a predetermined flow rate at the longitudinal direction; arranging a pair of upper rollers and a lower roller in parallel at the outlet side of the nozzle in which a predetermined gap is maintained between the upper rollers and the lower roller, wherein multiple convex molds extending from the upper rollers to the predetermined gap are formed on the circular surface of the upper rollers; rotating the upper rollers and the lower roller at opposite directions and introducing the molten metal through the predetermined gap, and at the same time flowing a coolant in the upper rollers and the lower roller to semi-solidify the molten metal, thereby obtaining a porous metal sheet from the predetermined gap. Therefore, an integrated and mass manufacturing process for a porous metal sheet is achieved which can effectively save the punch waste generated
