1. An imaging module comprising:

  • a solid state image sensor having a light-receiving surface and configured to receive light and to perform photoelectric conversion on the received light to generate an electrical signal;

    a substrate having a conductor layer and extending from the solid state image sensor in a direction opposite to where the light-receiving surface is provided, along an optical axis direction of the solid state image sensor;

    a multi-layer substrate on a surface of the substrate, the multi-layer substrate having therein a plurality of conductor layers and a plurality of via holes;

    a plurality of electronic components mounted on or in the multi-layer substrate;

    an image signal electrode pad on the solid state image sensor;

    a drive signal electrode pad on the solid state image sensor;

    an image signal cable for transmitting an image signal;

    a drive signal cable for transmitting a drive signal;

    an image signal wiring pattern through which the image signal is transmitted from the image signal electrode pad to the image signal cable; and

    a drive signal wiring pattern through which the drive signal is transmitted from the drive signal cable to the drive signal electrode pad, whereinat least one of the plurality of electronic components is embedded inside the multi-layer substrate, andthe image signal wiring pattern and the drive signal wiring pattern are separated on a side of the solid state image sensor into different conductor layers of the substrate and the multi-layer substrate due to the at least one of the plurality of electronic components embedded inside the multi-layer substrate, thereby to allow the image signal and the drive signal to be transmitted to the image signal cable and the drive signal electrode pad, respectively, through the different conductor layers of the substrate and the multi-layer substrate.
