Please add the following new Abstract of the Disclosure:

An ultrasonic wave generation device and system for inhibiting decreased intensity of an ultrasonic wave owing to adhesive. A waveguide (13) separate from an ultrasonic wave converging part (12) that is adhered to an ultrasonic wave generation source (11) adhesive (20). When a line projecting an outer circumferential edge (11B) of the source (11) onto a reflection surface (16) along an advancing direction of an ultrasonic wave generated from the source (11) is defined as imaginary line (L1), and straight lines passing through points on line (L1) and focus (Fs) for the reflection surface (16) are defined as imaginary lines (L2), and a line formed by intersection points between a reflection surface (17) and the lines (L2) is defined as imaginary line (L3), the adhesive (20) is, on an inner circumferential side relative to the source (11), provided in a region on an outer circumferential side relative to line (L3).
