To provide a semiconductor device which can increase reliability with respect to external force, especially pressing force, while the circuit size or the capacity of memory is maintained. A pair of structure bodies each having a stack of fibrous bodies of an organic compound or an inorganic compound, which includes a plurality of layers, especially three or more layers, is impregnated with an organic resin, and an element layer provided between the pair of structure bodies are included. The element layer and the structure body can be fixed to each other by heating and pressure bonding. Further, a layer for fixing the element layer and the structure body may be provided. Alternatively, the structure body fixed to an element layer can be formed in such a way that after a plurality of fibrous bodies is stacked over the element layer, the fibrous bodies are impregnated with an organic resin.
