An adhesive tape includes a foam base and an adhesive layer disposed on at least one surface of the foam base. The foam base has a 25% compressive strength of 250 kPa or more. An average bubble diameter in a machine direction and an average bubble diameter in a cross-machine direction of the foam base are each 150 μm or less, and a ratio represented by the average bubble diameter in the machine direction/an average bubble diameter in a vertical direction and a ratio represented by the average bubble diameter in the cross-machine direction/the average bubble diameter in the vertical direction are each 5 or less. With this adhesive tape, in addition to good conformability to an adherend and excellent impact resistance, suitable reworkability can be realized even when the adhesive tape has a small width.
