Abstract
An adhesive tape including a particular foam base is provided. An average bubble diameter in a machine direction (MD) and an average bubble diameter in a cross-machine direction (CD) of the foam base are each 150 μm or less, the ratio of the average bubble diameter in the machine direction/an average bubble diameter in a vertical direction (VD) and the ratio of the average bubble diameter in the cross-machine direction/the average bubble diameter in the vertical direction are each 6 or less, and the foam base has an interlaminar strength of 20 N/cm or more. With this adhesive tape, good followability to an adherend and excellent impact resistance can be realized. The adhesive tape of the present invention can be suitably used in portable electronic devices, such as smartphones, tablets, notebooks, and game machines, whose screen size has been increasing and for which a requirement for flexible design is high.
