Disclosed is a film for laser processing, which has excellent processing precision, while being improved in quality of a processed surface. Specifically disclosed is a film for laser processing, which is used for a thermal processing using a laser light. This film for laser processing is characterized by being made of a polymer material containing an additive which causes an endothermic reaction when thermally decomposed. L'invention porte sur un film pour traitement au laser, qui présente une excellente précision de traitement tout en présentant une qualité améliorée d'une surface traitée. De façon spécifique, l'invention porte sur un film pour traitement au laser qui est utilisé pour un traitement thermique utilisant une lumière laser. Ce film pour traitement au laser est caractérisé en ce qu'il est fait d'une matière polymère contenant un additif qui provoque une réaction endothermique lorsqu'il est décomposé thermiquement.
