Summary:Disclosed is a method of manufacturing a multilayered chip power inductor by forming a laminate body having upper and lower sides by laminating magnetic sheets, forming an inner hollow by punching out a middle part of said laminate body, inserting a magnetic core into the inner hollow, where an electrical conductive coil is wound into said inner hollow, laminating a first copper clad magnetic sheet onto the upper and lower sides of said laminate body having the magnetic core in the inner hollow as a land layer having upper and lower sides, forming a land by etching said land layer, forming a hole by drilling the land, plating the hole formed in the land, laminating a second copper clad magnetic sheet as a terminal layer onto upper and lower sides of the land layer having the land, forming a terminal by etching the terminal layer, forming a hole by drilling the terminal, and plating the hole.
