  • Publication number: 20230114992
    Abstract: Disclosed herein are relates to a method for compressing a laminate and a method for manufacturing a ceramic electronic component including a laminate. The method for compressing a laminate includes: preparing a laminate; pressurizing the laminate from a first pressure to a second pressure; heating the laminate from a first temperature to a second temperature; maintaining compression of the laminate at the second pressure and the second temperature for a predetermined time; cooling the laminate from the second temperature to a third temperature; and depressurizing the laminate from the second pressure to a third pressure, wherein the second temperature is 70° C. to 150° C.

  • Patent number: 11145464
    Abstract: A multilayer ceramic capacitor includes a ceramic body including an active portion that includes a dielectric layer and a plurality of internal electrodes overlapping each other across the dielectric layer, and cover portions formed above and below the active portion, and including first and second surfaces opposing each other, third and fourth surfaces connecting the first and second surfaces, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other, and first and second side margin portions disposed on the first and second surfaces. In a cross-section of the ceramic body in a length-thickness (L-T) direction, a ratio Sd/Sc of an area Sd of a region except for the active portion to an overall area Sc of the cross-section is greater than 27%.
