Abstract
Abstract A bar code label comprises a recording medium and a bar code recorded on a recording medium. The bar code includes a plurality of bar elements lined up parallel. Each width of bar elements is different in accordance with the kind of bar elements. The width of the bar elements is made wider than it would normally be based on its distance from the center of the bar code toward the end of the bar code.
