- レーザー光を透過させると共に一部を吸収して発熱する樹脂フィルムの一方の面側にレーザー光を照射することで、レーザー光が照射された領域に凹部を形成する樹脂フィルムの加工方法において、
樹脂フィルムの他方の面に樹脂フィルムよりも高い割合でレーザー光を吸収して発熱する発熱層を形成し、樹脂フィルムの一方の面における発熱層に対応した領域にレーザー光を照射することで樹脂フィルムにおけるレーザー光が照射された領域の一方の面側を発熱させると共に、樹脂フィルムを透過したレーザー光を発熱層が吸収して発熱することで樹脂フィルムにおけるレーザー光が照射された領域の他方の面側を加熱することにより、レーザー光を照射した領域の樹脂フィルムの両面の対応する位置に一対の凹部を形成することを特徴とする樹脂フィルムの加工方法。 - 前記樹脂フィルムは、オレフィン系樹脂を用いて構成されることを特徴とする請求項1に記載の樹脂フィルムの加工方法。
