A dielectric paste used for fabrication of a capacitor which permits manufacture of a small-sized ceramic oscillator by being incorporated in the oscillator. The dielectric paste comprises powdered glass, dielectric powder, and an organic vehicle. The dielectric powder is a lead-based perovskite compound. The powdered glass includes a main component given by xSiO2-yB2O3-zPbO (where x, y, and z are expressed in mole percent). The x, y, and z lie within a region defined by connecting points A (x=70, y=0, and z=30), B (x=70, y=15, and z=15), C (x=10, y=75, and z=15), and D (x=10, y=0, and z=90). Preferably, at least one member selected from the group consisting of Al2O3, CaO, TiO2, ZrO2, BaO and MgO is used as an additive. Preferably, glass frit accounts for about 35-95% by weight of the mixture of the powdered glass and the dielectric powder, and the dielectric powder accounts for about 5-65% by weight.
