A mounting structure includes a first ceramic electronic component including a ceramic body including internal electrodes and outer electrodes. When a voltage is applied to the outer electrodes, the ceramic body is strained with a first strain amount, and a second ceramic electronic component including a ceramic body including internal electrodes and outer electrodes. When a voltage is applied to the outer electrodes, the ceramic body is strained with a second strain amount greater than the first strain amount. The second ceramic electronic component is arranged above the first ceramic electronic component, and the first and second ceramic electronic components are connected to each other via each other's outer electrodes. The first ceramic electronic component to which the second ceramic electronic component is connected is connected to a land on a circuit substrate via the outer electrodes of at least the first ceramic electronic component.
