ABSTRACT:
In order to prevent static electricity impairment of an electronic component, a layer at the surface of a container to be in contact with an electronic component is one having a relatively high surface resistivity, a layer having a higher electrical conductivity than that is laminated below it, and the surface resistivity of the layer at the surface is higher than that of the layer below it. It is considered that in an electronic component packaging container having such a constitution, static electricity electrified on an electronic component is gradually discharged from the electronic component to the surface of the electronic component packaging container without sudden discharge, thus preventing the static electricity impairment. The surface layer preferably comprises a material close to the electronic component in the series of frictional electrification.
