Abstract
【解決手段】 熱硬化性樹脂剤13には、その光吸収率が最高となる波長よりも長い波長を有するレーザ光Lが照射される。これにより、レーザ光Lが入射する表面部13sで吸収されるレーザ光Lの光量が減少し、内部13iに到達するレーザ光Lの光量が増加する。加えて、熱硬化性樹脂剤13でのレーザ光Lの散乱が抑制され、内部13iにレーザ光Lが進行し易くなる。従って、表面部13sだけでなく内部13iも十分に加熱されて、熱硬化性樹脂剤13の全体が硬化する。更に、レーザ光Lは、表面部13sから内部13iに収束するように表面部13sから内部13iに入射させられる。このことと、表面部13sで吸収されるレーザ光Lの光量が減少することが相俟って、表面部13sでの損傷の発生が防止される。
