摘要： PROBLEM TO BE SOLVED: To provide a laminated inductor and a method of manufacturing the same whereby a characteristic is prevented from being degraded by the influence of a magnetic field caused by a current passing through a conductor pattern, a magnetic property is prevented from being degraded by residual stress generated in a magnetic substance due to a difference in the coefficient of thermal expansion between the conductor pattern and the magnetic substance, and the magnetic property is prevented from being degraded by silver which is used for the conductor pattern and diffused into magnetic substance layers.
SOLUTION: The magnetic substance layers and the conductor pattern are stacked and the conductor pattern between the magnetic substance layers is connected to form a coil in a laminate. At this point, the conductor pattern is formed using conductor paste in which silver powder is coated with SiO
2 . The conductor paste contains 0.05 to 0.3 wt% of SiO
2 in terms of the weight of the silver.
