The invention provides a hard and soft integrated electronic product shell, comprising a rigid part formed by foamed metal and a flexible part formed by a polymer elastomer, wherein the foamed metal is fixedly connected with the polymer elastomer. According to the electronic product shell provided by the invention, a rigid framework is provided by using the foamed metal, and excellent rigidity can be achieved; and meanwhile, the polymer elastomer and the foamed metal are fixedly connected and are inserted to each other to form the locking force, and thus the metal and the elastomer are combined very firmly and cannot easily disconnect; and moreover, the appearance of the shell can be an integrated elastomer, and thus the consistency between the appearance effect and the hand feeling can be maintained.
