Abstract
In an electronic component, electrodes defining functional portions are provided on a piezoelectric substrate. In order to define a hollow portion which the functional portions face, there are provided a first support with a frame shape, and second supports on the piezoelectric substrate in an inner side region surrounded by the first support. A cover is laminated on the first support as well as on the second supports to define the hollow portion. A height of each of the second supports is higher than a height of the first support.
