Abstract
An optical section (3) and a lens holder (4) are fixed to each other in a state where the lens holder (4) is at an intermediate position within a movable range so that the optical section (3) does not come into contact with an image pickup section (10) in a case where the lens holder (4) is driven within the movable range. This makes it possible to provide (i) a camera module in which it is possible to reduce the influence of a tilt that occurs in the vicinity of an infinite-distance side mechanical end and also reduce the influence of a tilt that occurs at an intermediate position away from the infinite-distance side mechanical end and a macro side and in which image pickup lenses are attachable with high positional accuracy and (ii) a method for producing a camera module.

1-13. (canceled)
A method for producing a camera module, the camera module including:
- an optical section including a plurality of image pickup lenses;
- a lens driving device including:
- a lens holder configured to hold the optical section;
- and
- a movable range limiting section configured to limit a movable range for the lens holder on an infinite-distance side and a macro side,
- the lens driving device being configured to drive the optical section and the lens holder integrally at least along an optical axis of the plurality of image pickup lenses;
- and
- an image pickup section including an image pickup element,
- the image pickup section being disposed on the infinite-distance side of the optical section and the lens driving device,
- the method comprising:
- a first step of positioning the optical section with respect to the lens holder with use of a jig while sliding the optical section on the lens holder in a state where the lens holder is at an intermediate position within the movable range;
- and
- a second step of fixing the optical section to the lens holder at a position at which the optical section has been positioned through the first step.

- an image pickup section including an image pickup element,
- the image pickup section being disposed on the infinite-distance side of the optical section and the lens driving device,
- the method comprising:
- a first step of positioning the optical section with respect to the lens holder by causing the optical section to abut on either a fixing section of the lens driving device or part of the image pickup section in a state where the lens holder is at an intermediate position within the movable range;
- and
- a second step of fixing the optical section to the lens holder at a position at which the optical section has been positioned through the first step.
