This movement learning device is provided with: a first movement characteristic extraction unit (102) which extracts characteristics of trajectories of movement of skilled workers and ordinary workers on the basis of moving image data obtained by capturing images of the skilled workers and the ordinary workers; a movement characteristic learning unit (103) which clusters trajectory characteristics that are among the extracted trajectory characteristics and that are similar to a determined reference trajectory characteristic, generates a histogram of the clustered trajectory characteristics on the basis of the frequencies of occurrence of these clustered trajectory characteristics, and performs discriminative learning for identifying trajectory characteristics of skilled movements, on the basis of the generated histogram; and a discriminative function generation unit (104) which refers to the discriminative learning results, and generates a discriminative function indicating a boundary for discriminating between skilled and unskilled movements.
