Abstract
An ultrasonic probe has a transduction layer in which a plurality of transducers are placed, a backing layer provided at a rear side of the transduction layer with a wiring layer therebetween, and a plurality of heat dissipation members provided in the backing layer. The plurality of heat dissipation members extend in a line form in the backing layer, and are placed with an aligned direction of extension. An area occupancy percentage of the heat dissipation member at a center region of the backing layer is larger than that at an outer side of the center region. The center region is not positioned at ends of the cross section intersecting the direction of extension of the heat dissipation member, includes a center of gravity of the cross section, and occupies an area less than or equal to a half of an area of the cross section.
