Ultrasound probe and information acquisition device including ultrasound probe

An ultrasound probe comprising:

• electrostatic capacitance type transducers with each transducer comprising:
• a vibration film which includes a first electrode;
• and
• a second electrode which is provided with a space between the vibration film and the second electrode;
• and
• a supporting member that has a curved surface on which a plurality of transducers are provided;
• a reception circuit that receives current output by a change in an electrostatic capacitance between the first electrode and the second electrode and that converts the current into voltage;
• and
• wiring configured to electrically connect the transducer and the reception circuit and provided inside the supporting member,
• wherein an inner wall surface of the supporting member includes a plurality of recessed flat surface parts, and the transducers are provided on the recessed flat surface parts with plate-like substrates therebetween,
• wherein perpendicular lines for the plurality of recessed flat surface parts of the supporting member cross each other at a single point on an inner side of the supporting member, and normal lines for reception surfaces of the plurality of transducers cross each other at the single point, and
• wherein the reception circuit is provided on an opposite side of a side where the transducers are provided and outside the supporting member.
