Multilayer capacitor and board having the same mounted thereon

A multilayer capacitor comprising:

• a capacitor body including dielectric layers and first and second internal electrodes, the capacitor body having a first surface and a second surface opposing each other, a third surface and a fourth surface, connected to the first surface and the second surface and opposing each other, and a fifth surface and a sixth surface, connected to the third surface and the fourth surface and opposing each other, the first internal electrode being exposed through the third, fifth, and sixth surfaces, and the second internal electrode being exposed through the fourth, fifth, and sixth surfaces;
• a first side portion and a second side portion, respectively disposed on the fifth surface and the sixth surface of the capacitor body;
• and
• a first external electrode and a second external electrode, respectively connected to the third surface and the fourth surface of the capacitor body to be respectively connected to the first internal electrode and the second internal electrode,
• wherein the first and second side portions comprise an second phase including a glass comprising aluminum (Al) and silicon (Si), manganese (Mn), and phosphorus (P),
• wherein each of the first and second side portions has an average thickness of 10 to 20 μm, and
• wherein the capacitor body comprises an active region, in which the first and second internal electrodes overlap each other, and upper and lower cover regions, respectively disposed on upper and lower surfaces of the active region.
