PROBLEM TO BE SOLVED: To provide a coating type magnetic tape having excellent electromagnetic conversion characteristics and reliability/durability as a medium while recording capacity is large and total thickness is thinned and having excellent tape type interchange performance. SOLUTION: In the magnetic tape having a magnetic layer containing magnetic powder and a binder on one surface of a non-magnetic substrate via an under layer containing non-magnetic powder and a binder and a back layer on the other surface, total thickness of the tape is 4.0 to 5.4μm, at least one of the under layer and the magnetic layer contains a fatty acid amide, an extraction amount of the fatty acid amide extracted from the magnetic layer side by n-hexane is 0.5 to 1.5 mg/cm<SP>3</SP>and the fatty acid amid has≥70°C melting point.
