A method of manufacturing a capacitor component includes preparing a laminate structure in which a plurality of ceramic sheets, each having an internal electrode pattern formed thereon, are layered, attaching an auxiliary member to an upper surface and a lower surface of the laminate structure, and disposing the laminate structure having the auxiliary member attached thereto on a lower mold on which jigs for blocking a length direction portion and a width direction portion of the laminate structure are disposed and compressing the laminate structure. The ceramic sheet has a thickness of 0.6 μm or less, and the auxiliary member has higher elasticity than elasticity of the lower mold.
