PROBLEM TO BE SOLVED: To provide a laminated-layer inductor of chip-size 1005 type for realizing a high Q-value. SOLUTION: An electric insulating layer and a conductive pattern are mutually laminated, and an edge part of each conductive pattern is sequentially connected, to form a coil 5 superimposed in a laminated direction in the electric insulating layer body 2. At the same time, the edge part of the coil 5 is connected to outer electrodes 3 and 4 through drawing conductors 6 and 7 to fabricate a laminated inductor 1 with a size of 1 mm×0.5 mm×0.5 mm. In a laminated chip of 4 nH or smaller, the coil 5 has a conductor width of 60μm or larger, a conductor thickness of 20μm or larger, and a conductor interval of 20μm or larger. In a laminated chip of 4 nH or larger, the coil 5 has a conductor width of 30 to 60μm, a conductor thickness of 20μm or larger, and a conductor interval of 20μm or larger.
