The shape retention of the glass layer or the baking electrode layer is good, and the surface of the glass layer is smooth and the appearance is good. It is excellent in soldering heat resistance and solder adhesion, has no change in resistance value by plating treatment of the baking electrode layer, and has a high anti-stiffness.;The dormer 10 includes a pair of insulating glass layers 14 covering both the ferromagnetic body 11 and the ferromagnetic body 11 except both end faces of the ferromagnetic body 11 and a pair of end portions 11, And terminal electrodes 12, The terminal electrodes 12 and 12 hold the baking electrode layer 16 formed at both ends of the element 11 and the plating layers 18 and 19 formed on the surface of the electrode layer 16 respectively. And a part or the whole of the glass layer 14 is formed of a crystallized glass.;Representative drawing: First drawing
