A cart-type ultrasound diagnostic apparatus includes a recess portion disposed at an outer side surface of a casing that constitutes an apparatus body of the ultrasound diagnostic apparatus； a probe connector that is disposed in the recess portion and to which a connection terminal of an ultrasound probe is connectable； and a cover member disposed at the outer side surface of the casing so as to cover the recess portion. The cover member, in a state in which the connection terminal of the ultrasound probe is connected to the probe connector, covers the recess portion and allows a cable of the ultrasound probe to be led out from inside of the recess portion to outside of the recess portion.
