Claim:
1. An image sensor unit that reads light having been emitted to an object of illumination, comprising: a light source; a light guide that includes a light emitter having an emission surface from which light is emitted toward said object of illumination, and a bent portion that is bent from an end of said light emitter and has, at an end face, an incident surface on which the light from said light source is incident; a light condenser that focuses light from said object of illumination; an image sensor that receives the light focused by said light condenser, and converts the light into an electric signal; a circuit board that mounts said light source and said image sensor on one surface; and a frame that houses said light guide, said light condenser and said circuit board, wherein said frame includes a light blocking portion that protrudes toward said one surface of said circuit board at a position between said light source and said image sensor, and on said one surface of said circuit board, a conductive portion continuously overlapping with an external line of said light blocking portion in a sub-scan direction in a view of said circuit board in a direction orthogonal to said one surface is formed.
