PROBLEM TO BE SOLVED: To provide ferrite parts and a module which are capable of easily and precisely forming a magnetic gap and are slightly influenced by a use environment and are capable of reducing a variation with time of an inductance value, and to provide methods of manufacturing the ferrite parts and the module. SOLUTION: A lamination constituted by laminating plural ferrite green sheets comprises a first through-hole formed in the laminating direction, and an insulator made of non-magnetic ceramics at a temperature of -40°C or more arranged in the first through-hole. The first through-hole is provided as a distributed magnetic gap by sintering the lamination. COPYRIGHT: (C)2007,JPO&INPIT
