The present invention is a dielectric magnet composition, which is characterized in that it contains a first component and a second component, and the content ratio of the first component to the total number of mols relative to the oxide-converted first component is 0 to 35.85 mol%. Oxide of Ca, oxide of 0 to 47.12 mol% of Sr, oxide of 0 to 51.22 mol% of Ba, oxide of 0 to 17.36 mol% of Ti, oxide of 0 to 17.36 mol% of Zr, 0 ~ 2.60mol% of the oxide of Sn, 0 ~ 35.32mol% of the oxide of Nb, 0 ~ 35.32mol% of the oxide of Ta, 0 ~ 2.65mol% of the oxide of V, the first component contains a selective At least one of an oxide of Ca, an oxide of Sr, and an oxide of Ba, at least one selected from the oxides of Ti and Zr, and an oxide selected from the oxides of Nb and Ta At least one of these is an essential component, and relative to the total number of moles of the first component in terms of oxide, the total of Ca oxide in CaO, SrO equivalent in Sr oxide, and BaO equivalent in Ba oxide. The content ratio is 48.72 ~ 51.22 mol%. The total content ratio of Ti oxide converted to TiO 2 , Zr oxide converted to ZrO 2 and Sn oxide converted to SnO 2 is 15.97. ~ 17.36mol%, of the total content ratio of Nb 2 O 5 Nb in terms of oxide, Ta 2 O 5 and Ta oxide in terms of V 2 O 5 in terms of an oxide of V is 31.42 ~ 35.31mol%, and the The dielectric magnet composition contains at least an oxide of Mn as a second component. According to the present invention, it is possible to provide a method that can be fired in a reducing atmosphere and has a high relative dielectric constant. When used as a dielectric layer of a ceramic electronic component such as a multilayer ceramic capacitor, it can be electrostatically charged even at 150 to 200 ° C. Dielectric capacitor composition with less change in capacitance and less dielectric loss at 25 ° C and 200 ° C. |
