The mobile information terminal comprises a first casing having an operation unit on the surface, a second casing having a display unit on the surface, and a joint mechanism. This joint mechanism joints the first casing and the second casing in an openable manner, and joints the first casing and the second casing such that the display unit can be shifted in the open state between the transversely long state and the longitudinally long state with respect to the first casing. A hinge pin for jointing the first casing and the second casing in the openable manner is positioned in the closed state above the second casing with respect to the surface of the first casing.
