Abstract
A thin film device is provided, in which inductance can be increased when a thin film coil wound on a magnetic film is provided. In a thin film coil wound on a magnetic film, thickness of lower coil portions is smaller than thickness of upper coil portions. Consequently, a magnetic property (permeability) tends to be hardly deteriorated.
