Manufacturing method of multilayer ceramic electronic component

A method of manufacturing a multilayer ceramic electronic component, comprising steps of:

• preparing a ceramic green sheet comprising ceramic powder;
• forming an internal electrode pattern with a conductive paste comprising conductive metal particles and an additive on the ceramic green sheet;
• laminating a ceramic green sheet on which the internal electrode pattern is formed to form a ceramic laminate;
• and
• plasticizing the ceramic laminate to form a ceramic body comprising a dielectric layer and an internal electrode,
• wherein, when an average thickness of the dielectric layer is referred to as td and a standard deviation of a thickness of the dielectric layer in each position is referred to as σtd, while an average thickness of the internal electrode is referred to as te and a standard deviation of a thickness of a pre-determined region of any layer of the internal electrode in each position is referred to as σte, a ratio (σte/σtd) of the standard deviation of the internal electrode in each position to the standard deviation of the thickness of the dielectric layer in each position satisfies 1.10≤σte/σtd≤1.35.
