Imaging device and electronic apparatus

An electronic apparatus, comprising

• an imaging device including
• a first semiconductor substrate having a first surface and a second surface and including a sensor pixel that performs photoelectric conversion,
• a second semiconductor substrate having a third surface and a fourth surface and including a readout circuit that outputs a pixel signal based on electric charge outputted from the sensor pixel, the second semiconductor substrate being stacked on the first semiconductor substrate with the first surface and the third surface opposed to each other, and
• a wiring layer provided between the first semiconductor substrate and the second semiconductor substrate and including a first wiring line and a second wiring line that are electrically coupled to each other, one of the first wiring line and the second wiring line being in an electrically floating state while another of the first wiring line and the second wiring line is electrically coupled to a transistor provided to the first semiconductor substrate or the second semiconductor substrate.
