PROBLEM TO BE SOLVED: To solve such problems that when a conductive material is used for a sponge formed product which is widely used as a packaging material for an optical element module having parts with difficulty for handling such as gratings and loose tubes, the carbon in the conductive material easily drops and this means not only the module can not be carried to a clean room but deterioration in the performance such as short circuits in the module may be caused by the deposition of carbon. SOLUTION: The optical element module is housed in a conductive tray in which a conductive material is kneaded so as to avoid dropping of carbon. An antistatic air cap sheet on which pairs of air bubbles with a little smaller gap than the width of the grating part are arranged is applied so that the grating is interposed between the air bubbles. Then a conductive cover is applied to cap the conductive tray.
