PROBLEM TO BE SOLVED: To provide a dielectric glass composition which is included in a laminate common mode choke coil having a structure where a dielectric glass layer is sandwiched with magnetic material portions comprising ferrite or the like, is good in sinterability at a temperature around 900°C, and hardly causes structural defects.SOLUTION: A dielectric glass composition includes 5-40 wt.% of a filler component comprising quartz and 60-95 wt.% of a frit component, and the frit component contains 60.0-89.0 wt.% of Si in terms of oxides, 0.1-3.5 wt.% of Mg in terms of oxides, 10.0-32.0 wt.% of B in terms of oxides, and 0.3-4.0 wt.% of K in terms of oxides. A laminate common mode choke coil includes a dielectric glass layer comprising the dielectric glass composition. |
