| 摘要 |
The present invention relates to a bonding sheet including: an adhesive layer of an adhesive composition having a high-molecular weight component (A) and a thermosetting component (B) formed into a sheet, wherein a ratio (PCN/PCO) of a peak height near 2240 cm−1 derived from a nitrile group (PCN) to a peak height near 1730 cm−1 derived from a carbonyl group (PCO) is 0.03 or less in an IR spectrum of the high-molecular weight component (A). |
