Device for surface mounting and capacitor element

A device for surface-mounting, comprising:

• a substrate;
• and
• a capacitor element loaded on a loading-side surface of the substrate,
• wherein the device is integrally molded including the substrate and the capacitor element using a packaging resin,
• the substrate includes, on the loading-side surface, a first connecting electrode electrically connected to an anode electrode of the capacitor element and a second connecting electrode electrically connected to a cathode of the capacitor element, and, on a mounting-side surface, a first terminal electrode connected to the first connecting electrode and a second terminal electrode connected to the second connecting electrode respectively by through electrodes,
• wherein the first terminal electrode and the second terminal electrode include electrode portions respectively disposed next to each other around a circumference of the mounting-side surface of the device, the electrode portions of the second terminal electrode being disposed on all portions of all sides of the circumference except where the electrode portions of the first terminal electrode are disposed, at least one of the second connecting electrode and the second terminal electrode including a center electrode portion that covers a center part of the substrate, and a shield electrode that substantially continuously covers from the center part to the circumference of the substrate being configured by at least one of the second connecting electrode and the second terminal electrode that are connected with the cathode of the capacitor element.
