Zusammenfassung:PROBLEM TO BE SOLVED: To reduce the size of a pinhole and the number of pinholes in an adhesive tape.SOLUTION: The adhesive tape includes an adhesive layer 12 as an adhesive, wherein the adhesive layer comprises an adhesive composition 16, an air bubble 20, and an inorganic hollow particle 18. The inorganic hollow particle 18 contains Na, Si, and Ca. The mass ratio (Na/Si) of Na to Si, contained in the hollow particle 18, is 0.1 to 0.3 inclusive. The concentration of Ca contained in the hollow particle is 34,000 ppm or larger.
