PROBLEM TO BE SOLVED: To provide an imaging element and imaging apparatus for suppressing power consumption by controlling a circuit operation band upon horizontal transfer. SOLUTION: A column A/D circuit 150 includes a horizontal adder 153 for horizontal readout. The horizontal adder 153 includes: an adder 11, that is a one-bit full adder, disposed between column A/D circuits 150 of neighboring two columns (in vertical direction); a flip-flop 12 that outputs a carry bit in response to a clock signal; and a selector 13 for switching a connection to a data storage unit 152 in response to an MSB control signal from a timing control unit 140. The adder 11 reads and adds digital image signals, in a bit-by-bit manner, from LSB sides of the data storage units 152 in the column A/D circuits 150 of the neighboring two columns and stores them in an MSB side of the data storage unit 152 in one of the columns.
