Abstract:
1. A solid-state imaging element comprising: a sensor substrate including a photoelectric conversion section; a circuit substrate including a circuit configured to drive said photoelectric conversion, said circuit substrate being laminated to said sensor substrate; a sensor side electrode drawn out to a surface of said sensor substrate on a side of said circuit substrate and formed as a projection electrode, wherein at least a portion of said projection electrode projects from the surface of said sensor substrate on the side of said circuit substrate; and a circuit side electrode drawn out to a surface of said circuit substrate on a side of said sensor substrate, formed as a depression electrode, and joined to said sensor side electrode in a state of said circuit side electrode and said sensor side electrode being fitted together, wherein at least a portion of said depression electrode recedes from the surface of said circuit substrate on the side of said sensor substrate.
