PROBLEM TO BE SOLVED: To prevent a beautiful appearance from being damaged by an observed pattern caused by unevenness when securing easiness of air ventilation by forming the unevenness on the surface of an adhesive layer so that the air may not be held at sticking. SOLUTION: The adhesive sheet 10 has many convex bodies 2a attached to the surface of the adhesive layer 2 on a base material sheet 1 so that the width w of a groove-shaped valley part 2b between the convex bodies 2a and the height h of the convex body may satisfy the relation of w≤h. Ordinarily, a base layer 2c is formed under the convex bodies, and the adhesive layer is formed out of the convex bodies and the base layer. When the top parts of the convex bodies form a top panel part 2d, each of the area is preferably regulated so as to be≤100 mm<SP>2</SP>. A releasing sheet 3 having a releasing surface having a convex and concave pattern reverse to the convex and concave pattern of the adhesive layer is preferably laminated on the adhesive layer.
