Patent ID: 11527362

Abstract:
A multi-layer ceramic capacitor includes: a first region including a polycrystal including, as a main component, crystal grains free from intragranular pores; a second region that includes a polycrystal including, as a main component, crystal grains including intragranular pores and includes a higher content of silicon than a content of silicon in the first region; a capacitance forming unit including ceramic layers laminated along a first direction, and internal electrodes disposed between the ceramic layers; and a protective portion including a cover that covers the capacitance forming unit and constitutes a main surface facing in the first direction, a side margin constituting a side surface facing in a second direction orthogonal to the first direction, and a ridge constituting a connection portion, the connection portion connecting the main surface and the side surface to each other. The ceramic layers include the first region. The ridge includes the second region.
