Abstract
An imaging device, a manufacturing method of an imaging device, and an information code reading device configurable not only to simplify their optical system and to reduce their costs, but also to suppress fluctuations of resin lenses and deterioration of lens performances due to its expansion. An optical system has a second lens made of resin and the other lenses made of glass. The power of the resin lens is small in comparison with that of the glass lens, wherein each power is set to be small in comparison with that of the optical system. In the lens frame structures, the lens holding part and the imaging element holding part are separately constituted, the lens holding part and imaging element holding part are fastened through the intermediate member, expansion coefficients of the lens holding unit and the imaging element holding unit are different so as to control the coefficients.
