A distributed learning technology that can accelerate convergence while ensuring security is provided. A learning step of generating, by an i-th client, a modelwin a j-th cycle using learning data D, an aggregation step of generating, by a server, a global modelwin the j-th cycle from the modelsw, . . . ,win the j-th cycle according to a predetermined formula, and an end condition determination step of, by the server, ending learning processing with the global modelwin the j-th cycle as the global modelwin a case where a predetermined end condition is satisfied, and otherwise, transmitting the global modelwin the j-th cycle to the i-th client, and an initialization step of setting, by the i-th client, the global modelwin the j-th cycle as an initial value of a modelwin a j+1-th cycle are included.
