We have investigated elastic properties of the mixed-valent intermetallic compound YbPd by means of ultrasonic measurements on the single-crystals. A pronounced elastic anomaly (elastic softening) was observed at around the transition temperature T1≈130 K with a significant hysteresis, being indicative of a first-order phase transition. Furthermore, it was found that the elastic anomaly showing up around T1 was hardly affected by application of a magnetic field, suggesting the non-magnetic origin. We can analyze quantitatively the temperature dependence of all measured elastic modes C11 and C44 with a Jahn-Teller formula. Our findings suggest that the pronounced elastic softening toward T1 will enable us to predict the possible charge ordering origin.
