There are provided a coil-embedded dust core that provides high inductance and a method for manufacturing the same. The coil-embedded dust core includes a coil 1 formed by winding a flat conductor 2 and a green body 10 comprising of ferromagnetic metal powder coated with an insulating material. The coil 1 is composed of a winding section 3 in which the flat conductor 2 having front and back surfaces opposed to each other with a predetermined distance is wound and lead-out end sections 4a and 4b that are extended from the winding section 3. Either one of the front and back surfaces of the lead-out end section 4a and either one of the front and back surfaces of the lead-out end section 4b are formed so as to be on the same plane. By using the coil 1 in which the both end sections (lead-out end sections 4a and 4b) are formed on the same plane, the coil-embedded dust core can be made smaller in size, and high inductance can be provided.
A coil-embedded dust core comprising:
A coil-embedded dust core comprising a green body formed of ferromagnetic metal particles coated with an insulating material and a coil which is embedded in said green body, wherein
A method for manufacturing a coil-embedded dust core in which a coil is embedded in a green body, comprising:
A coil comprising a winding section in which a flat conductor having front and back surfaces opposed to each other with a predetermined distance, is wound;
A method for manufacturing a coil, comprising:
