PROBLEM TO BE SOLVED: To provide a miniaturized and practical capsule endoscope to be assembled easily. SOLUTION: This capsule endoscope forms an image of an object image illuminated by an illuminator and formed by an objective lens in an image sensor and transmits image signals from the image sensor by radio. The capsule endoscope has an electric element holder barrel integrally formed with a main block supporting the objective lens and the illuminator, and a circuit board on which an image sensor control board for holding the image sensor and at least one more circuit board are connected in order with connecting strip control boards. The image sensor control board and at least one more circuit board are disposed with intervals, with the image sensor control board as the nearest to the objective lens, inside the electric element holder barrel.
