    Abstract: An image pickup device includes: a base board provided with an image sensor; an outer frame member fixed on the base board for shielding at least the image sensor; an optical member having a lens portion that forms an image of an object on a light-receiving surface of the image sensor and an outer form that supports the lens portion and is fitted in the outer frame member; a pressing member for urging the optical member in a direction of an optical axis of the lens portion with prescribed pressing force, to bring the optical member into contact with the base board or with the image sensor; and a rotation-preventing mechanism provided on an interfitting part where the optical member is fitted in the outer frame member for preventing rotation of the optical member around the optical axis.

    Abstract: An optical system (1,2) has an optical functional surface including a common region (A) used for conducting information recording and/or reproducing for both of a first optical information recording medium and a second optical information recording medium. The common region (A) comprises a refractive surface (A,1) of an imaginary basic aspherical surface and an optical path difference providing structure (A,2) in which plural ring-shapes zones are separated around the center of an optical axis and neighboring ring-shaped zones are displaced to each other in a direction of an optical axis so as to cause an optical path difference obtained by multiplying a predetermined wavelength lambda s ( lambda 1
