Provided is an adhesive sheet capable of achieving a further improvement in quality while achieving excellent air release properties. According to the present invention, provided is an adhesive sheet provided with: a film-like base material; and an adhesive layer provided on at least one surface of the film-like base material. The adhesive sheet is further provided with a coating layer which partially covers the surface of the adhesive layer. The adhesive surface of the adhesive sheet is formed by the adhesive layer and the coating layer. The coating layer is provided with sections which extend linearly from one end to another end of the adhesive surface. Furthermore, the sections which extend linearly are provided with: first surfaces which form the adhesive surface of the adhesive sheet; and second surfaces which are located at the adhesive-layer side with respect the first surfaces. The second surfaces of the sections which extend linearly are each formed as an overall gentle curve in a cross section orthogonal to the length direction of the sections which extend linearly.
