PROBLEM TO BE SOLVED: To shorten time of dynamically measuring resolution for adjusting an inclination amount of a lens section to an image sensor during manufacturing so that an entire image forming face is in focus.SOLUTION: A manufacturing method of a camera module includes a lens section adjusting process for adjusting an inclination amount during fitting of a lens barrel 2 as a lens section which condenses image light to an image sensor 1 that photoelectrically converts the image light from a subject and performs imaging. In the lens section adjusting process, resolution of a formed image in the image sensor 1 is measured in a plurality of places on an image forming face for each inclination amount of the lens barrel 2, a plurality of relations of the resolution (contrast) to the inclination amount of the lens barrel 2 are acquired, a coefficient is obtained from the plurality of acquired relations between the inclination amount and the resolution to derive an approximation function, and the inclination amount during fitting of the lens barrel 2 in which the entire image forming face is in focus is obtained by using the approximation function. |
