Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an imaging apparatus, processing circuitry and permission input circuitry. The imaging apparatus includes an imaging system performing X-ray imaging of an object, and a bed on which the object is placed.

Abstract: When a connection object is connected to a connector, an upper jaw portion of a first terminal presses an upper contact point against an upper signal line. Hence a lower signal line is pressed against a lower contact point so that a contact point support portion is pressed against a stop portion of a housing. At least a part of force applied to the stop portion acts as force to deform downward an upper wall of a receiving portion for receiving a lower jaw portion of the first terminal. A reinforcing portion of the lower jaw portion of the first terminal reinforces the upper wall from beneath. Since strength necessary for the upper wall can be reduced, the housing can be downsized and thus the connector can be downsized.
