Solid-state imaging apparatus

A solid-state imaging apparatus including a first substrate on which a plurality of photoelectric conversion units are arranged and a second substrate on which a plurality of readout circuits to process or read a signal generated by each of the photoelectric conversion units are arranged, the solid-state imaging apparatus comprising:

• a plurality of first conductive patterns which are arranged on the first substrate and electrically separated from one another;
• and
• a plurality of second conductive patterns which are arranged on the second substrate and electrically separated from one another,
• wherein each of the plurality of first conductive patterns has a first electrical connection portion to be in contact with at least one of the second conductive patterns, and wherein each of the plurality of first conductive patterns has a first electrical connection portion to be in contact with at least one of the second conductive patterns, and
• wherein the first conductive pattern includes a first partial pattern that includes the first electrical connection portion and extends in a first direction, and the second conductive pattern includes a second partial pattern that includes the second electrical connection portion and extends in a second direction different from the first direction, and
• wherein the second partial pattern has a length extending in the second direction longer than a length thereof in the first direction.
