A plurality of internal electrodes is disposed inside the ceramic body, connected to the first and second surfaces, and have one ends connected to the third and fourth surfaces. First and second side margin parts are disposed on end portions of the internal electrodes connected to the first and second surfaces. The ceramic body includes an active portion forming capacitance by including the plurality of internal electrodes disposed to oppose each other with the dielectric layer interposed therebetween. An average Sn content in a region adjacent to the side margin part of the active portion is greater than an average Sn content in a central region of the active portion.
