Abstract:
1. A capsule endoscope comprising: an illumination board section on which an illumination portion is arranged; a lens support member that supports a lens; a hole that pierces through the illumination board section, the lens support member being fitted in the hole; a supporting portion that positions and supports the illumination board section with respect to the lens support member when the lens support member is inserted into the hole, the supporting portion being provided in the lens support member; and an imaging board section on which an imaging sensor is arranged, wherein a flexible wiring board section made of a flexible material connects the illumination board section and the imaging board section so that the illumination board section and the imaging board section are integrally formed; wherein the lens support member is positioned with respect to the imaging sensor and includes: a large diameter portion that is positioned with respect to the image sensor, is formed on one end side of the lens support member, and has an outer diameter of a predetermined size; a small diameter portion that is inserted into the hole, is formed on other end side of the lens support member, and has an outer diameter smaller than the outer diameter of the one end side; and a step portion that is formed at a boundary between the large diameter portion and the small diameter portion; wherein the supporting portion positions and supports the illumination board section with respect to the lens support member by abutting the illumination board section against the step portion when the other end side of the lens support member is inserted into the hole; wherein an electronic component having a predetermined height is arranged on the imaging board section, the electric component driving the image sensor, and wherein a length in a height direction from the imaging board section to the step portion formed in the lens support member is longer than a length in the height direction of the electronic component.
