Abstract
A laminated coil component includes a magnetic material part containing a metal magnetic material and a first glass component, and a nonmagnetic material part containing a ceramic material and a second glass component, and a coil conductor is formed so that at least the main surface of a coil pattern is in contact with the nonmagnetic material part. The magnetic material part is formed with the volume content of the first glass component based on the total amount of the metal magnetic material and the first glass component is 46 to 60 vol %. The nonmagnetic material part is formed with the volume content of the second glass component based on the total amount of the ceramic material and the second glass component is 69 to 79 vol %. A laminated coil component having good high-frequency characteristics and magnetic characteristics is obtained and a method for producing the laminated coil component.
