The present invention relates to borosilicate glass compositions for a sintering agent, dielectric compositions containing the borosilicate glass compositions and a multilayer ceramic capacitor using the dielectric compositions. Borosilicate glass compositions for a sintering agent according to an aspect of the invention include an alkali oxide, an alkaline earth oxide and a rare earth oxide, can sinter ceramic dielectrics at low temperatures and improve the hot insulation resistance of a multilayer ceramic capacitor. Correspondingly, dielectric compositions including these borosilicate glass compositions and a multilayer ceramic capacitor using the dielectric compositions can be sintered at a low temperature of 1100° C. or less and have high hot insulation resistance, thereby ensuring high levels of reliability.
