Abstract

Provided is a multilayer ceramic capacitor that can be reduced in size with increased capacity and also has high reliability. In a laminate 10 of the multilayer ceramic capacitor, when a region in which internal electrode layers 30 overlap with one another when viewed from a lamination direction T is defined as an effective part 11, facing regions which sandwich the effective part 11 from the width direction W are respectively defined as a first side surface-side outer layer portion WG1 and a second side surface-side outer layer portion WG2, and facing regions which sandwich the effective part 11, the first side surface-side outer layer portion WG1, and the second side surface-side outer layer portion WG2 from the lamination direction T are respectively defined as a first main surface-side outer layer portion TG1 and a second main surface-side outer layer portion TG2, the porosity Pw (%) of the first side surface-side outer layer portion or the second side surface-side outer layer portion, and the porosity Pwt (%) of the first main surface-side outer layer portion TG1 or the second main surface-side outer layer portion TG2 satisfy the relational formula (1). 1.6 ≤ Pwt − Pw ≤ 3.1 <img class="EMIRef" id="803ea74d-b5d0-464b-9397-ea031311c5e6-ia01" />
