In a hinge apparatus for rotatably connecting a first housing and a second housing of an electronic apparatus, the hinge apparatus includes a first rotating portion adapted to be connected to the first housing and a second rotating portion adapted to be connected to the second housing and rotatable with respect to the first rotating portion. The second rotating portion unrotatably holds a switch. A cam member is disposed to face the switch. The cam member is rotatable with respect to the second rotating portion and adapted to be engaged with the second housing in a rotating direction of the hinge apparatus. The switch includes a conductive first contact and a conductive second contact faced to the first contact and adapted to be connected to and disconnected from the first contact. The cam member has a cam portion for pressing the second contact following the rotation of the cam member to connect and disconnect the second contact to and from the first contact.
