The present technology relates to a semiconductor device and electronic equipment in which a semiconductor device that suppresses the occurrence of noise by a leakage of light can be provided.A semiconductor device is configured which includes a light-receiving element 34, an active element for signal processing, and a light shielding structure 40 which is between the light-receiving element 34 and the active element to cover the active element and is formed of wirings 45 and 46. The semiconductor device further includes a first substrate on which the light-receiving element is formed, a second substrate on which the active element is formed, and a wiring layer which has a light shielding structure by the wirings which is formed on the second substrate, and in which the second substrate can be bonded to the first substrate through the wiring layer.
