    Abstract: 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 %.

    Abstract: A multilayer coil component includes an element body, a coil including a plurality of internal conductors, and a plurality of stress-relaxation spaces. The plurality of internal conductors are separated from each other in a first direction in the element body. Each stress-relaxation space is in contact with a surface of the corresponding internal conductor and powders exist in each stress-relaxation space. The element body includes element body regions located between the internal conductors adjacent to each other in the first direction. Each stress-relaxation space includes a first boundary surface with each internal conductor and a second boundary surface with each element body region. The first boundary surface and the second boundary surface oppose each other in the first direction. A distance between the first boundary surface and the second boundary surface is smaller than a thickness of each element body region in the first direction.

    Abstract: An electronic component includes a body and a pair of terminal electrodes. The body has a pair of end faces opposing each other in a first direction, a pair of main faces opposing each other in a second direction, and a pair of side faces opposing each other in a third direction. One of the main faces serves as a mounting face. A clearance in the first direction between an end edge of a conductive resin layer and the end edge of a base metal layer at an end portion of the one of the main faces in the third direction is longer than a clearance in the first direction between the end edge of the conductive resin layer and the end edge of the base metal layer at a central portion of the one of the main faces in the third direction.
