PROBLEM TO BE SOLVED: To obtain a cover tape exhibiting good antistatic effects without detriment to clarity by forming a heat seal layer and then a vapor-deposited metal layer on one side of a cover tape substrate. SOLUTION: This cover tape 4 comprises a cover tape substrate 10, a heat seal layer 12 formed on the whole underside of the substrate 10 and a vapor- deposited metal (e.g. aluminum) layer 14 formed on the heat seal layer 12 and having a surface resistivity of 20-500Ω/(square). On the exposed surface of the vapor-deposited metal layer 14, an oxidation prevention layer in an amount of 0.1-10 mg/m2 is formed from SiOX (1<=x<2), etc., for preventing corrosion, The earring body comprises a band-like carrier tape having pockets 6 for containing parts and a band-like cover tape 4 stuck to the carrier tape so as to seal the pockets, After electronic parts W are put into the pockets 6, the cover tape 4 is heat-sealed to seal the pockets 6. Thus, the carrying body is used.
