  • Patent number: 11532438
    Abstract: A multilayer electronic component includes a multilayer body including dielectric layers and inner electrode layers. Each of the dielectric layers includes first crystal grains defining and functioning as plate-shaped objects that have an average thickness of less than or equal to about 300 nm and an average aspect ratio of more than or equal to about 5, each of the inner electrode layers includes second crystal grains defining and functioning as plate-shaped objects that have an average thickness of less than or equal to about 150 nm and an average aspect ratio of more than or equal to about 5, where an aspect ratio is represented by a ratio of a major axis of each plate-shaped object to a thickness of the plate-shaped object with the major axis of the plate-shaped object being orthogonal or substantially orthogonal to a thickness direction of the plate-shaped object.

  • Patent number: 11315730
    Abstract: A multilayer electronic component having an electrode facing portion in which a plurality of internal electrode layers face one another with a dielectric layer interposed therebetween. Each dielectric layer includes Ba, Ti, Si, Re, and M. M is at least one element selected from Mn, Ni, Co, Fe, Cr, Cu, Mg, Li, Al, Mo, W, and V. When the Ti is represented in an amount of 100 parts by mole the dielectric layer at the electrode facing portion has Si in an amount a of 0.01?a?0.1, Re in an amount b of 0.1?b?3.0, and M in an amount c of 0.2?c?5.0. A ratio m of the amount of Ba to the amount of Ti is 0.965?m?0.990.
