provided is a highly reliable imaging module that can easily carry out optical axis adjustments and focus adjustments while assuring required light shielding performance , and in which malfunctions do not easily occur in solder junctions and the like for imaging elements even under severe temperature environments . an imaging module has , in addition to a lens holding member , an imaging element , and a substrate on which the imaging element is mounted , a shielding member that is for preventing extraneous light from entering the imaging surface of the imaging element and on which a ring - shaped or notched ring - shaped protrusion for shielding is provided . the shielding member is held between the lens holding member and the substrate without the protrusion for shielding coming into contact with another member .
