Method for making electronic parts |
摘要 |
Electronic parts, such as an inductor, of improved connectivity between magnetic and conductive materials are made by sintering magnetic material under a condition in which no accumulation is developed, by forming a hollow-core of a shape different from an external shape of said conductive material through said magnetic material to be molded by an extrusion-molding means while inserting said magnetic material into said hollow-core, or by providing an erasable means to be removed by a heat treatment in said conductive material and conducting extrusion molding so as to embed said conductive material into said magnetic material, said erasable means being removed during a sintering treatment to form a space between said conductive material and said magnetic material, and a method for making same.
