摘要： A cover tape is provided for sufficiently suppressing corrosion of a metal part of an electronic component, even when the electronic component is stored in a high temperature and high moisture environment for a long period of time, and a carrier tape system for packing the electronic component is provided for stably obtaining a suitable peeling strength at the time of peeling the cover tape. The cover tape is provided with at least a base layer and a heat seal layer, and has; (1) an antistatic layer, which includes an antistatic agent and an antirust, and is formed on the surface of the heat seal layer, or (2) an average surface roughness (Ra) of 0.3-1.0μm on the seat seal layer side, and has an antistatic layer whereupon an antistatic agent is applied on the surface.
