Disclosed is an image pickup device which makes it possible to reduce the number of parts, to achieve a reduction in assembly man-hours, to meet the demand for a reduction in size, to facilitate the adjustment of the focal length, and to prevent the focal length from going out of adjustment after the adjustment of the focal length. A package 3 accommodating an image sensing device 4 is integrally combined with an optical component holding member 8a holding an optical component for forming an image of an object on the surface of the image sensing device 4, with a certain positional relationship between the optical component and image sensing device in the X, Y and Z-directions being determined, by engaging an engagement step portion 15 with an engagement claw 16. Further, a focal length adjusting spacer 19 is arranged between the package 3 and the optical component holding member 8a, and a biasing member 18 for biasing the optical component 10 toward the package 3 is provided between the image sensing device accommodating package 3 and the optical component 10.
