Abstract
A packaged device includes a device substrate and a packaging unit. The device substrate includes a first surface and a device formed in the device substrate. The packaging unit includes an insulating layer which faces the device substrate. The insulating layer includes a second surface bonded to the first surface. A metal concentration of at least part of a peripheral surface in the insulating layer is higher than a metal concentration of an end surface on the device substrate side in the insulating layer. An outline of the first surface is retreated inward from an outline of the second surface.
