Abstract

PURPOSE:To obtain a fine coil assembly with high output, by processing the conductive film in spiral, after forming the conductive film on the insulation film formed on the magnetic substance member, in an electromagnetic sensor such as magnetic head for audio devices. CONSTITUTION:In a magnetic head core of a cassette recorder, for example, an SiO2 insulation film 2 is provided over one curved part of the center part to another curved part, of a core 1 made of magnetic member, and after vapor depositing or bonding the conductive film such as metal on it, a thin coil 3 is formed by forming the coil 3 with etching. Thus, with the coil 3 which is negligible in the area than the sectional area of the core 1, a fine coil assembly without much space can be obtained as high output product without winding the wires.
