A laminated electronic component comprising: a plurality of parallel first conductive patterns, which are laminated via a magnetic layer to a plurality of parallel second conductive patterns, the first and second conductive patterns being alternately connected to each other via through-holes, thereby forming a spiral coil inside a laminated body, the axis of the spiral coil being parallel to a mount face; wherein the magnetic layer, provided between the plurality of first conductive patterns and the plurality of second conductive patterns, comprises non-magnetic sections which are provided at positions corresponding to ends of the conductive patterns and extend parallel to the axis of the coil, and a method for manufacturing the same.

Method for manufacturing laminated electronic component

Laminated electronic component and manufacturing method

A method for manufacturing a laminated electronic component, in which magnetic layers and conductive patterns for coil are sequentially provided, a coil pattern is enclosed between the magnetic layers inside a laminated body, and a nonmagnetic section is provided between adjacent conductive patterns for coil, the coil pattern being provided by repeatedly performing: a first step of providing a second magnetic layer over the entire top face of a first magnetic layer, which a first conductive pattern for coil is provided on; a second step of providing a loop-shaped groove in the second magnetic layer by using laser processing; a third step of providing a nonmagnetic section in one portion of the loop-shaped groove; and a fourth step of printing a second conductive pattern for coil so that one end section thereof overlaps the end section of the first conductive pattern for coil and the other end section extends to the surface of the nonmagnetic section.
