PROBLEM TO BE SOLVED: To provide an easily adhesive polyester film for a key top which has excellent strength, thermal resistance, dimensional stability, moldability, and good adhesiveness to ink, and does not cause the ink to peel off when a resin at a high temperature is injected on a formed part of the film, and does not reduce the handleability even if the amount of an added filler is reduced to impart transparency. SOLUTION: The easily adhesive polyester film for the key top has a coating film of a composition containing a polyester resin and an acrylic resin having an oxazolyl group and a polyalkylene oxide chain on at least one side of a biaxial oriented polyester film whose melting point is 210 to 245°C.
