Zusammenfassung:To reliably protect a pattern printed layer, without performing a front-to-back printing.SOLUTION: A circuit board 30 for an information recording device comprises a first base material 30a and a second base material 30b. A pattern printed layer 41, a background layer 42 and a plurality of conductive parts 38 are formed in this order, on the face of the second base material 30b side of the first base material 30a. A conductive pattern 18 connectable to the conductive part 38 is formed on the face of the first base material 30a side of the second base material 30b.SELECTED DRAWING: Figure 5A 【課題】表裏印刷を行うことなく、かつ絵柄印刷層を確実に保護する。【解決手段】情報記録装置用の回路基板30は、第1基材30aと第2基材30bとを備えている。第1基材30aの第2基材30b側の面に、絵柄印刷層41と背景層42と複数の導電部38がこの順で設けられている。第2基材30bの第1基材30a側の面に導電部38と接続可能な導電パターン18が設けられている。【選択図】図5A
