Claim Text:
1. An image sensor comprising: a substrate; photoelectric transducers and switching elements formed in layers on the substrate in this order, each of the photoelectric transducers including a hydrogenated amorphous silicon layer, each of the switching elements including an amorphous oxide semiconductor layer; and a blocking layer arranged between the hydrogenated amorphous silicon layers of the photoelectric transducers and the amorphous oxide semiconductor layers of the switching elements, the blocking layer suppressing penetration of hydrogen separated from the hydrogenated amorphous silicon layers, wherein the blocking layer includes a film made of SiC, and the photoelectric transducers receive light traveling toward a top of the substrate, the top of the substrate being a side where the photoelectric transducers are formed, and the blocking layer has a laminated structure in which the film made of SiC is sandwiched by SiN films.
