Abstract
A structure according to an embodiment includes a first substrate including a first valve and a second substrate joined to the first substrate. The structure includes a region where the first valve and the second substrate are not joined. A sticking suppressing section is provided in at least one of the first valve and the second substrate in the region. By configuring the structure in this way, it is possible to suppress sticking of the first valve to the second substrate in the structure including the first substrate including the first valve and the second substrate joined to the first substrate.
