The invention discloses a test device for an active layer material based on ultrasonic and temperature field. The test device is provided with an objective table for loading the active layer material, wherein a heating plate is arranged at the bottom of the objective table; the objective table is horizontally fixed on a bracket through a connector; an ultrasonic receiving plate and an ultrasonic emitting plate are respectively arranged on the upper part and the lower part of the objective table; an ultrasonic wave emitted from the ultrasonic emitting plate passes through the objective table and then is received by the ultrasonic receiving plate. According to the test device provided by the invention, the ultrasonic and the temperature field are smartly integrated on an instrument; the ultrasonic magnitude and the temperature can be changed according to the experimental requirements; the contrast test can be performed in the test process, so that the optimal ultrasonic magnitude and the value of the temperature can be detected; the invention innovatively adopts a tape casting method for causing the active layer solution to dry and form into the film under an effect of external field, so that the external field acts on the growth process of the active layer film and the structure of the active layer can be preferably changed; the instrument is low in manufacturing cost, is convenient and is easy to use; and the test result completely meets the expected requirements.
