PROBLEM TO BE SOLVED: To provide an adhesive tape for both sides and adhesive sheets which reduce limitlessly possibility of generating corrosion of the inside of an electronic device, poor movement and error operation, since they are used for adhesion to a cover material of the electronic device and different members of the inside of the electronic device, do not contain a silicone resin composition in a mold-releasing layer and regulate an impurity amount of an ionic impurity, etc., in an extremely low level while having the good mold-releasing property of a separated liner. SOLUTION: A double-sided adhesive tape and adhesive sheets use a release liner consisting of a mixture of polyethylene and an ethylene-propylene copolymer and use an acrylate copolymer as a man component wherein the surface tension is not less than 40 mN/m (23 deg.C), an amount of a volatile organic compound generated when heating an adhesive at 120 deg.C is not more than 10μg/cm2, and an amount of each ionic impurity in the adhesive is not more than 0.1μg/cm2, respectively.
