A contact type image sensor includes a plurality of opaque metallic films formed on top of a transparent insulating substrate. Each opaque metallic film is located between adjacent lower electrodes formed on a transparent insulating film so as to prevent light emitted from a light source from being irradiated on a document to be scanned. Further, each opaque metallic film is located between adjacent upper extension electrodes connected to transparent conductive films formed on photoelectric conversion layers, so as to prevent the light from being irradiated on the document. Only light which is emitted from the light source and then passes through the light window, is irradiated on the document.
