The present invention provides a disposable sheet including: a waterproof layer formed of a plastic sheet; an intermediate colored layer formed of a water-based solvent absorbent material containing a dye soluble in a water-based solvent; and a non-colored layer formed of a water-based solvent absorbent material thereon. A key is associated with a particular destination or with a particular piece of content. On this test pattern appears, for example, not only landing position shift caused by the rolling posture change of the carriage but also synthesized position shift caused by a plurality of kinds of posture changes of the carriage. A seed layer is formed over the barrier layer, and the TSV opening is filled with a conductive filler.
