Abstract

A method of manufacturing a laminated coil component is a method of manufacturing a laminated coil component provided with a laminate obtained by laminating a coil conductor forming a spiral coil and an insulator layer. The method of manufacturing a laminated coil component includes a step of providing a conductor pattern configured to become a coil conductor on a green sheet configured to become an insulator layer, and a step of laminating a plurality of green sheets provided with the conductor pattern. The conductor pattern includes a pair of first side surfaces opposed to each other in an orthogonal direction orthogonal to a laminating direction of the green sheet. At the step of laminating a plurality of green sheets, a depression is formed on at least one of the pair of first side surfaces.

Claims (10)

1. A method of manufacturing a laminated coil component provided with a laminate obtained by laminating a coil conductor forming a spiral coil and an insulator layer, the method comprising steps of:

providing a conductor pattern configured to become the coil conductor on a green sheet configured to become the insulator layer; and

laminating a plurality of green sheets provided with the conductor pattern,

wherein the conductor pattern includes a pair of first side surfaces opposed to each other in an orthogonal direction orthogonal to a laminating direction of the green sheets, and

a depression is formed on at least one of the pair of first side surfaces at the step of laminating the plurality of green sheets.

2. The method for manufacturing a laminated coil component according to claim 1 ,

wherein the depression is formed on each of the pair of first side surfaces at the step of laminating the plurality of green sheets.

3. The method of manufacturing a laminated coil component according to claim 1 ,

wherein the conductor pattern includes a second side surface brought into contact with the green sheet at the step of providing the conductor pattern and a third side surface opposing to the second side surface, and

after the step of laminating the plurality of green sheets, the second side surface is flatter than the third side surface.
