Solid-state image sensing apparatus and electronic apparatus to improve image quality of an image

An electronic apparatus, comprising:

• a solid-state image circuit configured to generate a signal electric charge by receiving incident light;
• a signal processing circuit positioned on a surface of the solid-state image circuit and configured to process an image signal output from the solid-state image circuit;
• and
• a multi-layer wiring package including the solid-state image circuit, the signal processing circuit, a first wiring layer and a second wiring layer, wherein
• the first wiring layer has heat conductivity higher than or equal to heat conductivity of the second wiring layer, and
• the first wiring layer is a ground wiring.
