In a laminate product formed by an organic member and/or an inorganic member, high strength adhesion between the organic member and the inorganic member is achieved by providing an adhesion layer which includes amorphous carbon nitride (a-CNx:H) particularly between the organic member and the inorganic member. Further, in order to protect a laminate product formed by an organic member and/or an inorganic member, for example, an organic electronic element including an organic compound layer, such as an organic electroluminescence element, a protective film including at least amorphous carbon nitride and a protective layer having a laminate structure formed by sandwiching a vapor deposition inorganic film between plasma polymerized films are used. Thus, a protective film which is optimum to an organic electronic element, having high bending stress resistance, high shielding effect against moisture and oxygen existing in the air, and excellent resistance to high temperature and high humidity can be provided.
