An image reading apparatus includes a transport path through which a medium to be read is transported, an image reading section disposed in a middle of the transport path and reading an image formed on the medium to be read that is transported along the transport path, a cover member that covers the image reading section and the transport path, a pressing member in which another end is supported by the cover member to cause one end to be swingable, thereby pressing the transported medium to be read against the image reading section, a circuit board member which is disposed on the cover member, and on which a grounded electric circuit is formed, and a conductive member which electrically connects the pressing member to the electric circuit formed on the circuit board member to ground the pressing member through the electric circuit.
