The invention provides a capacitor assembly and a capacitor built-in substrate. The capacitor assembly includes a body including a first surface and a second surface opposite to each other in a first direction, a first internal electrode, a second internal electrode, a first dielectric layer interposed between the first internal electrode and the second internal electrode, and a second dielectric layer provided on the second internal electrode are wound around the first direction as a winding axis; a first external electrode disposed on the first surface and connected to the first internal electrode; and a second external electrode disposed on the second surface and connected to the second internal electrode. The first internal electrode and the second internal electrode include different metals. 本公开提供一种电容器组件和电容器内置基板。所述电容器组件包括：主体，包括在第一方向上彼此相对的第一表面和第二表面，其中，在所述主体中，第一内电极、第二内电极、介于所述第一内电极和所述第二内电极之间的第一介电层、以及设置在所述第二内电极上的第二介电层以所述第一方向作为卷绕轴卷绕；第一外电极，设置在所述第一表面上并连接到所述第一内电极；以及第二外电极，设置在所述第二表面上并连接到所述第二内电极。所述第一内电极和所述第二内电极包括不同
