A solid-state imaging device for enlarging an operating margin of a pixel portion and achieving complete transfer of a signal charge by using a plurality of power supply voltages, wherein a plurality of power supplies having different power supply voltage values are supplied to portions of a semiconductor chip 1. For example, as a first power supply system, a first digital power supply voltage (DVDD 1 ) is supplied from a power supply terminal 45 , a first digital ground voltage (DVSS 1 ) is supplied from a power supply terminal 46 , a second digital power supply voltage (DVDD 2 ) is supplied from a power supply terminal 47 , a second digital ground voltage (DVSS 2 ) is supplied from a power supply terminal 48 , a third digital power supply (DVDD 3 ) is supplied from a power supply terminal 49 , and a third digital ground voltage (DVSS 3 ) is supplied from a power supply terminal 50 , and as a second power supply system, a first analog power supply voltage (AVDD 1 ) is supplied from a power supply terminal 40 , a first analog ground voltage (AVSS 1 ) is supplied from a power supply terminal 41 , a second analog power supply voltage (AVDD 2 ) is supplied from a power supply terminal 42 , and a second analog ground voltage (AVSS 2 ) is supplied from a power supply terminal 43.
