Abstract

The present invention provides a carrier tape for storage use of super-miniaturized electronic components, by which the reflection of irradiated light which might cause detection errors cab be prevented, the product inspection can be performed easily and quickly, and number of stored pieces and remaining un-used pieces can be easily and quickly counted, when the presence or absence of deformation--which might take place on the lead portion of the electronic components being stored in the carrier tape--is examined by the optical equipment on the lead portion kept on the carrier tape. The surface of said base component can be treated to form a film to prevent the light reflection or to absorb the light, such as by painting with resins or ink which doesn't reflect the light, or by immersion. Alternatively, the color of the base component is selected to be black. Moreover, by providing holes for the piece-counting on the carrier tape at a certain intervals, the number of components in the storage area can be counted by the photo-electric tube through said holes.
