The invention discloses a test device of determining the recovery coefficient in metal material contact bump, comprising a metal ball, a metal plate, a speed sensor and an acquisition card. The metal ball is located above the metal plate; the metal ball and the metal plate are fixed in distance; the speed sensor is arranged on the metal plate; the acquisition card is in electric connection with the speed sensor. The test device has a simple structure, is easy to operate, can obtain an accurate collision recovery coefficient through testing the time change in a metal material contact bump process, is easier compared with traditional speed measurement and dynamic height measurement, and improves measurement precision.
