Adhesive sheet

The present invention provides a adhesive sheet capable of further improving quality while obtaining good exhaust properties. According to the present invention, there is provided the adhesive sheet including a film-shaped substrate and an adhesive layer provided on at least one surface of the film-shaped substrate. The adhesive sheet further includes a coating layer covering a part of the surface of the adhesive layer. The adhesive surface of the adhesive sheet is composed of the adhesive layer and the coating layer. The coating layer has a linear portion extending from one end to the other end of the bonding surface. In addition, the portion extending in a linear shape has a first surface constituting an adhesive surface of the adhesive sheet, and a second surface located on the pressure-sensitive adhesive layer side with respect to the first surface. In addition, the second surface of the linearly extending portion is composed of a gentle curve as a whole in a cross section perpendicular to the longitudina
