An image reading device, comprising:

• a housing with a document platen provided on an upper surface of the housing;
• a scanning body including a base provided to be reciprocally movable in a sub scanning direction in the housing and an image reader that is held by the base and reads a document placed on the document platen while moving in the sub scanning direction;
• and
• a flat cable having flexibility, one end of which is connected to the image reader to be parallel with the document platen, wherein
• the flat cable includes:
• a follow-up deformed section that is wired to extend along the sub scanning direction and deforms following a movement of the scanning body;
• and
• a bent section continuing into a side of the one end of the follow-up deformed section and being bent so that the flat cable is aligned in a main scanning direction to be parallel with the document platen,
• the bent section is arranged along a lower surface of the base, and
• the base includes a holder that holds the bent section on the lower surface of the base.
