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.

Abstract: A probe 12 includes a laminated block 24 in which a protective layer 50, an acoustic matching layer 52, a vibrator array 20, a backing member 54, a relay board 56, and an IC 22 are laminated. A temperature sensor unit 26 is provided on a side surface of the laminated block 24. The temperature sensor unit 26 is provided with a metal film 60 provided in the vicinity of an edge on the front-side (the transmission/reception surface side) of the side surface of the laminated block 24, so as to extend along the front-side edge, and a thermistor 62 to detect a temperature of the metal film 60. The metal film 60 exerts a detection region expansion function of expanding a temperature detection region of the thermistor 62 in a direction where a temperature gradient occurs in the wave transmission/reception surface of the probe 12. Further, the metal film 60 also exerts a thermal diffusion function of diffusing heat of the wave transmission/reception surface of the probe 12.
