Provided are a method for manufacturing an imaging-module and an imaging-module manufacturing device that can increase the flexibility of the component arrangement in an electronic device. A relative position of the lens unit and the imaging device unit, held on an axis perpendicular to a measurement chart, and the measurement chart on the axis is changed and images of the measurement chart are captured at the relative positions in the state where, when the lens unit is installed in an electronic device, a magnetic field having a magnitude equal to a magnitude of a magnetic field applied to the movable image-stabilizing unit is applied to the movable image-stabilizing unit. A compensation amount is calculated using signals acquired by capturing the images of the measurement chart, a tilt of the imaging device unit relative to the lens unit is adjusted, and the imaging device unit is fixed to the lens unit.
