Provided is a learning effect estimation device which can estimate a learning effect of a user by reflecting various aspects of a mechanism through which a person understands an object. The present invention comprises: a model storage unit which receives an input of learning data that is data of a learning result of a user to which a category for each learning purpose is allocated, and stores a model that generates a per-category correct answer probability of the user on the basis of the learning data; a correct answer probability generation unit which inputs the learning data to the model and generates the per-category correct answer probability; a correct answer probability database which accumulates, for each user, time-series data of the correct answer probability; and an intelligibility and reliability generation unit which acquires range data designating the range of a category for estimating a prescribed learning effect of the user, generates the intelligibility based on the correct answer probability within prescribed range data of the user and the reliability having a smaller value, as a variation in the time-series data of the intelligibility gets greater, and outputs the intelligibility and the reliability in association with the category.
