A solid-state imaging apparatus includes: a read out circuit configured to convert the analog signal generated by a pixel into a digital signal. The read out circuit includes an analog circuit, a digital circuit and a logic circuit arranged between the analog circuit and the digital circuit. The analog circuit is formed within first and second semiconductor regions of first and second conductivity type. The logic circuit is formed within third and fourth semiconductor regions of the first and second conductivity types. The digital circuit is formed within a fifth and sixth semiconductor regions of the first and second conductivity types. The first to sixth semiconductor regions are isolated one from another. And, a number of elements included in the logic circuit is smaller than a number of elements included in the digital circuit.
