PROBLEM TO BE SOLVED: To simplify a layout and to improve the quality by focusing on a structure of an electric charge discharging part for thinning in the columns direction. SOLUTION: A solid-state imaging apparatus has a sensor part 12 in which photoelectric converters 11 are arranged in a matrix, a vertical electric charge transfer part 14 transferring a signal electric charge read out from the sensor part 12 in rows, a horizontal electric charge transfer part 15 transferring the signal electric charge transferred by the vertical electric charge transfer part 14 in columns, and an electric charge discharging part 18 selectively preventing the transfer of the signal electric charge from the vertical electric charge transfer part 14 to the horizontal electric charge transfer part 15 in units of columns and discharging the prevented signal electric charge. The electric charge discharging part 18 is formed in the sensor part 12 at the horizontal electric charge transfer part 15 side, and has a high concentration region 42 having higher concentration than that of the sensor part 12.
