    摘要: The present invention provides a pressure-sensitive adhesive tape for a flexible printed circuit, from which a release liner can be released without being torn off even after being subjected to a high temperature process such as a solder reflow process. The pressure-sensitive adhesive tape of the present invention includes: a pressure-sensitive adhesive layer; and a release liner on at least one surface of the pressure-sensitive adhesive layer, wherein a tensile strength of the release liner in a machine direction is 50 MPa to 150 MPa, and a tensile strength of the release liner in a machine direction after heating at 280° C. for 5 min is 20 MPa to 120 MPa.
