    摘要： A glass ceramic composition of the present invention includes a main component composed of a first glass, a second glass, Al2O3, and SiO2. The first glass is SiO2—K2O—B2O3 based glass. The second glass is MO—SiO2—Al2O3—B2O3 based glass (“M” is an alkaline-earth metal) and/or CaO—SiO2—Al2O3—ZnO—ZrO2—B2O3 based glass. In case that the total amount of the main component is 100 wt %, the main component contains the second glass of 12 to 30 wt %, the first and second glass of 40 to 56 wt % in total, and further Al2O3 of 7 to 18 wt %.

    摘要： In a multilayer coil component, a coil is configured by electrically connecting coil conductors respectively provided in magnetic body layers constituting an element body and metal magnetic particles have a normal particle having an ellipsoidal shape and flat particles having an ellipsoidal shape flatter in a thickness direction than the normal particle. A plurality of the normal particles and at least one of the flat particles disposed such that a surface (reference surface) including a major axis direction orthogonal to the thickness direction and a minor axis direction is along the forming surface of the coil conductor in the magnetic body layer are arranged in the lamination direction of the magnetic body layers between the coil conductors.
