Abstract

The object of the present invention is to provide a cover tape for packaging an electronic part which enables the reduction of the production time, and decreases the defective fraction due to the temperature variation of the sealing trowel, the present invention provides a cover tape for packaging an electronic part which includes a base layer and a sealant layer, and is closely adhered to a carrier tape, wherein the sealant layer is made of a resin composition; a main component in the resin composition has a melting point of 100° C. or less; a peeling strength A under fixed measurement conditions after heat-sealing to a polycarbonate sheet through the sealant layer at 220° C. for 0.015 seconds and a peeling strength C under the fixed measurement conditions after heat-sealing to a polycarbonate sheet through the sealant layer at 180° C. for 0.015 seconds satisfy conditional expressions 1 and 2 below; and after peeling, a part of the sealant layer remains on a surface of the carrier tape to which the sealant layer is closely adhered; Conditional expression 1: 20 (g)≤A≤70 (g) and Conditional expression 2: 0.43≤C/A≤1.0.
