Abstract
An optical device for bar-code reading capable of improving the degree of freedom in design of component lenses so as to allow free positional adjustment of the lenses while ensuring downsizing and weight reduction of the device, and a method for manufacturing are disclosed. An optical device for bar-code reading comprises a light emitting element; a light projection lens for focusing light from the light emitting element so as to irradiate a bar code; a light receiving lens for focusing reflected light from the bar code and having formed therein a penetrating hole which penetrates a plane of incidence of light and a plane of outgoing of light, in which the light projection lens is inserted; and a light receiving element for receiving the light focused by the light receiving lens so as to perform photo-electric conversion.
