Dielectric composition and electronic component containing the same

An electronic component comprising:

• a body including a plurality of dielectric layers and internal electrodes;
• and
• external electrodes disposed on the body to be connected to the internal electrodes,
• wherein the dielectric layer contains:
• a base material powder containing BamTiO3 (0.995≤m≤1.010);
• a first accessory ingredient containing at least one element corresponding to a transition metal in Group 5 of the periodic table in a total content of 0.3 to 1.2 moles, based on 100 moles of the base material powder;
• a second accessory ingredient containing at least one of ions, oxides, carbides, and hydrates of Si in a content of 0.6 to 4.5 moles, based on 100 moles of the base material powder;
• a third accessory ingredient, distinct from the second accessory ingredient, containing at least one element in Period 4 or higher;
• and
• a fourth accessory ingredient containing at least one element in Period 3,
• wherein 0.70×B≤C+D≤1.50×B and 0.20≤D/(C+D)≤0.80, in which B is a total content of the second accessory ingredient, C is a total content of the third accessory ingredient, and D is a total content of the fourth accessory ingredient.
