IMAGING DEVICE

An imaging device is provided which includes a camera module, a case, a cover, a board, a terminal, and a connector housing. The camera module includes a holder in which a lens is disposed and an image sensor which captures an image in response to light having passed through the lens and outputs it in the form of an electrical signal. The cover defines an inner chamber along with the case in which the lens and, the holder and the image sensor are disposed. The board obtains the electrical signal from the image sensor. The terminal connects with the board to achieve transmission of the electrical signal therebetween. The connector housing has the terminal disposed therein. The holder includes a holder body and a flange. The holder body has light, as having passed through the lens, travel therein. The holder body is arranged adjacent to the connector housing in a first direction. The flange extends in the first direction from a portion of the holder body which faces the connector housing. The flange is secured to the case. If the flange is projected onto a plane in a direction perpendicular both to a direction in which an optical axis of the lens extends and the first direction, the connector housing overlaps the flange. This structure enables the overall size of the imaging device to be reduced.
