Light is illuminated from a back-surface side of a silicon substrate 4. A back-illuminated type imaging device 100 reads out, from a front-surface side of the silicon substrate 4, charges that are generated in the silicon substrate 4 in response to the illuminated light, so as to perform imaging. The back-illuminated type imaging device 100 includes pad portions 17 formed on the back surface of the semiconductor substrate 4, and a plurality of pillars 9 that are formed in the semiconductor substrate 4, are made of a conductive material and electrically connect wiring portions 12 formed on the front surface of the semiconductor substrate 4 and the pad portions 17 to each other.
