Patent ID: 8590123

Claim:
A method for producing an electronic component comprising: a magnetic body part containing at least NiO, ZnO, and Fe 2 O 3 ; and an internal conductor part containing Cu as its main constituent, the internal conductor part provided in the magnetic body part and partially extracted to a surface of the magnetic body part, the method comprising: a firing step of firing an unfired laminated body in an atmosphere with an oxygen concentration equal to or lower than an equilibrium oxygen partial pressure of Cu—Cu 2 O, the unfired laminated body having an unfired internal conductor material to serve as the internal conductor part after the firing, the unfired internal conductor material being provided in an unfired magnetic material to serve as the magnetic body part after the firing; and an oxygenic-atmosphere heat treatment step of subjecting a fired laminated body obtained by the firing in the firing step to a heat treatment in an atmosphere with an oxygen concentration of 0.01% or more in a subsequent temperature decrease process.
