1. An ultrasound probe, comprising:
a transducer array;
an electronic circuit provided behind the transducer array and electrically connected to the transducer array;
a backing provided behind the electronic circuit and configured to attenuate ultrasound waves from the transducer array; and
a shell having a shell head that retains the backing and configured to absorb heat from the backing, wherein
assuming that a direction in which the transducer array, the electronic circuit, and the backing are arranged is defined as a Z direction, a direction perpendicular to the Z direction is defined as an X direction, and a direction perpendicular to the Z direction and the X direction is defined as a Y direction,
in the backing, both of Z-direction thermal conductivity and Y-direction thermal conductivity are higher than X-direction thermal conductivity,
the backing has two outer surfaces intersecting the Y direction, and
the shell head has two inner surfaces joined to the two outer surfaces intersecting the Y direction.
