A solid-state image sensing apparatus includes a solid-state image sensing device, signal processing circuit device, and a multi-layer wiring package. The solid-state image sensing device has a pixel in an image sensing area thereof. The pixel receives incident light and generate a signal electric charge. The signal processing circuit device is arranged to face the image sensing area and applies signal processing to a signal output from the solid-state image sensing device. The multi-layer wiring package has wiring layers, the solid-state image sensing device, and the signal processing circuit device. Each of the wiring layers is laminated via an insulator. The multi-layer wiring package is formed such that a first wiring layer provided between the solid-state image sensing device and the signal processing circuit device has a greater thickness than second wiring layers and has heat conductivity higher than or equal to heat conductivity of the second wiring layers.
