    • PURPOSE: A method for manufacturing a gas sensor using a floating type carbon nano tube and a carbon nano tube nano structure and the gas sensor manufacture by the same are provided to obtaining an excellent gas sensing function because resistance variations can be sensitively measured because of added bonding of the carbon nano tubes. CONSTITUTION: A method for manufacturing a gas sensor using a floating type carbon nano tube is as follows. The gas sensor comprises a carbon nano tube nano structure as a sensing unit. A pair of micro electrodes is formed on a substrate(S1). The carbon nano tube is synthesized on a surface of the micro electrode by a chemical vapor deposition method. A mutual combination of the carbon nano tubes formed in each micro electrode is performed by an increase of the carbon nano tubes to a longitudinal direction(S2).
