An imaging device includes an image sensor on which an object image is formed via a photographing optical system; a radially-retracting device which moves the image sensor between a photographing position, at which the image sensor is located on a common optical axis of the photographing optical system, and a radially-retracted position; and a flexible PWB for electrically connecting the image sensor to an image processing circuit. The flexible PWB includes a fixed portion positioned in front of the retracted position of the image sensor, and a free-deformable portion extending from the image sensor toward the fixed portion. The free-deformable portion forms a shape to accommodate and cover the image sensor when the image sensor is radially retracted to the radially-retracted position, and is extended to form a shape to uncover the image sensor when the image sensor is positioned in the photographing position.
