1. An ultrasonic atomization apparatus comprising:
a container including a separator cup configured to accommodate a source solution at a lower part;
an internal hollow structure body including a hollow inside being provided above said separator cup in said container;
a water tank configured to accommodate an ultrasonic wave conveyance medium inside, said water tank and said separator cup being positioned so that a bottom surface of said separator cup is immersed in said ultrasonic wave conveyance medium; and
a plurality of ultrasonic vibrators provided in a bottom surface of said water tank, wherein
when a part of a plurality of incident waves transmitted from said plurality of ultrasonic vibrators is reflected on said bottom surface of said separator cup, a plurality of bottom surface-reflected waves is obtained,
said separator cup and said plurality of ultrasonic vibrators are provided to satisfy a reflected wave avoidance condition,
said reflected wave avoidance condition is a condition that “said plurality of bottom surface-reflected waves is not received by any of said plurality of ultrasonic vibrators”,
said bottom surface of said separator cup is formed into a spherical surface shape with a center projecting downward,
said plurality of ultrasonic vibrators are disposed to be separated apart from each other so as to have a same distance from a reference point of said bottom surface of said water tank,
said bottom surface of said water tank includes a plurality of reflected wave reception regions configured to receive said plurality of bottom surface-reflected waves,
said ultrasonic atomization apparatus further comprises a plurality of ultrasonic wave absorption members embedded in recess portions in said plurality of reflected wave reception regions,
a constituent material of each of said plurality of ultrasonic wave absorption members is a rubber material, and
said plurality of reflected wave reception regions are different from the regions where said plurality of ultrasonic vibrators are provided.
