    • The present invention provides a small, light, easy to handle and low-price apparatus which allows measurement or quantification of panniculus in a mode of use using a personal computer not only at specific facilities such as a medical institution but also at home. The present invention is constructed of a small, light ultrasonic probe, an ultrasonic oscillation element drive/detection circuit connected to ultrasonic oscillation elements housed in the probe through a multiplexer, a focusing circuit which makes an echo image transmitted through a reflected signal of ultrasound obtained from the detection circuit visually well defined by means of digital delays, a data communication circuit which transfers image information to the personal computer and transmits a control signal from the personal computer to a control circuit, a control circuit which controls the ultrasonic oscillation element drive/detection circuit, focusing circuit and data communication circuit, and measuring software which constitutes an interface of the apparatus on the personal computer. Of these components, components from the drive/detection circuit to the data communication circuit are housed in the measuring apparatus.
