The present invention relates to a capsule endoscope comprised to enable some parts thereof to expand in volume according to a pH to photograph stably regardless of a diameter of a digestive organ. The capsule endoscope comprises: an optical dome; a housing joined to the optical dome and embedded with a lighting optical system; an outer cover film joined to one side of the housing, embedded with a volume expansion material which expands in volume by the inflow of moisture, and made of a moisture penetrating texture; and a capsule film enclosing the outer cover film to protect the outer cover film and melted when a pH is greater than or equal to a certain value. |
