The paint film protecting sheet has the compatibility of the prevention of the occurrence of a microdeformation and a good peelability. That is, when an article such as automobiles having a paint film applied with the protecting sheet is placed outdoors for a long period of time at high temperature, the paint film is hard to deform and the sheet can be easily peeled even after adhering for a long period of time.
