PROBLEM TO BE SOLVED: To provide a cover tape for packaging electronic components, whose peeling strength has little dependence on the sealing temperature and which undergoes little deterioration with age, and allows a stable sealing capability. SOLUTION: The cover tape for packaging electronic components is a film comprised at least of three layers of a heat-sealant layer, an intermediate layer, and a substrate layer, the outermost layer being of a laminated biaxially-oriented film such as polyester, polypropylene or nylon, etc., and the intermediate layer adjacent to the heat-sealant layer showing a tensile strength in TD direction of 10 N/mm<SP>2</SP>or lower when formed into a film alone.
