PURPOSE:To make easily an electrode head which enables high-resolution recording by forming integrally a laminate consisting of an electric conductor layer and a support layer in a fixing compound and polishing only the support layer mechanically. CONSTITUTION:A stripe-shaped electrode 32 is formed on a polyimido film 31 using a laminate 34 copper. A fixing compound consisting of a mixture of powdered hexagonal boron nitride and uncured thermocuring resin is placed on the electrode and a support 31, an electrode 32 and a fixing compound 33 are integrally molded. This integral molding is made into an electrode head capable of 10 lines/mm. resolution by gringing only the support layer on a grinder with abrasives. By this manufacturing method which does not allow an electrode needle to protrude because of its soldering, an electrode head capable of high-resolution recording can easily bo obtained. The recommendable fixing compound is one containing 20-80wt% of hexagonal boron nitride. When a compound of talc and thermocuring resin is used as a fixing compound, it is recommended that the talc content be within a range of 30-80wt%. |
