Abstract:
A method for producing a multilayer electronic part comprising the steps of:superposing a plurality of sheets each on which an L- or a U-shaped coil conductor as an element of a plurality of coils is formed so that adjacent coil conductors are connected with each other via through holes formed in each sheet and filled with a conductive material to form a stack of coil sheets; superposing first and second lamination sheets without coil conductors on respective top and bottom portions of said stack of coil sheets, superposing first and second conductor sheets as terminal electrodes respectively on an upper and a bottom portions of the respective first and second lamination sheets each having a through hole filled with the conductive material of a leading portion of an individual coil conductor; press-fitting said conductor sheets, said first and second lamination sheets and said plurality of sheets; thereafter, cutting said press-fitted sheets into respective chip coils, and burning said coils to obtain the multilayer electronic part having the terminal electrodes comprised of a conductive layer structure member of the conductive sheets at opposite end portions.
