1. A multilayer capacitor comprising:
an element body including a pair of end surfaces facing each other, and a pair of side surfaces and a pair of main surfaces extending in a facing direction of the pair of end surfaces between the pair of end surfaces;
a plurality of first internal electrodes disposed in a facing direction of the pair of main surfaces in the element body and extending in the facing direction of the pair of end surfaces;
a plurality of second internal electrodes disposed in the facing direction of the pair of main surfaces in the element body and extending in a facing direction of the pair of side surfaces;
a pair of first external electrodes disposed on the pair of end surfaces to wrap around the pair of side surfaces and the pair of main surfaces; and
a pair of second external electrodes disposed on the pair of side surfaces to wrap around the pair of main surfaces and to be spaced apart from the first external electrodes, wherein
at least one of the pair of main surfaces is a curved surface which is curved in a convex shape,
when viewed from the facing direction of the pair of side surfaces, when a distance between a surface of the first external electrode at an apex position of the first external electrode and the main surface is defined as Ht, and a distance between the apex position and an apex position of the main surface in the facing direction of the pair of main surfaces is defined as Y, 0<Y<Ht is satisfied for each of the pair of first external electrodes at least on the curved surface side,
when viewed from the facing direction of the pair of end surfaces, a distance between a surface of the second external electrode at an apex position of the second external electrode and the main surface is defined as Hs, Ht>Hs is satisfied for each of the pair of second external electrodes on both sides of the pair of main surfaces, and
when viewed in the facing direction of the pair of main surfaces, when a distance between a surface of the first external electrode at an apex position of the first external electrode and the side surface is defined as Hw, and a distance between a surface of the second external electrode at an apex position of the second external electrode and the side surface is defined as Ts, Ts>Hw is satisfied for each of the pair of second external electrodes.
