Abstract
A packaged image sensor includes a first pipe and a second pipe, wherein the first pipe with a shorter length is initially encapsulated with an image sensor and a light-emitting element to define a relative position between the first pipe and the image sensor. The second pipe is connected to the first pipe and then is encapsulated in a second encapsulation process. The abovementioned packaged image sensor is easy to manufacture. An endoscope including the abovementioned packaged image sensor is also disclosed.
