Conductive adhesive tape and manufacturing method thereof

A conductive adhesive tape comprising:

• a first substrate that is formed in a nano-web form having a number of pores by spinning a polymer material by a spinning method;
• a non-porous film layer that is formed on one surface of the first substrate, and has an electrical conductivity;
• a first conductive adhesive layer that is laminated on the other surface of the substrate in a non-porous form by spinning a conductive adhesive material by the spinning method;
• and
• a conductive double-side tape that is formed on the non-porous film layer,
• wherein the conductive double-side tape comprises:
• a second substrate that is formed in a nano-web form having a number of pores by spinning the polymer material by the spinning method;
• a second conductive adhesive layer that is formed on one surface of the second substrate;
• and
• a third conductive adhesive layer that is formed on the other surface of the second substrate.
