A purchasing factor estimation device 30 comprises: an acquisition unit 31 that acquires person attribute information 301 relating to a first person and product attribute information 302 relating to a first product; an estimation unit 32 that, on the basis of the person attribute information 301 and the product attribute information 302, uses an estimation model 320 to estimate the first person's degree of interest in the first product; and an output unit 33 that outputs the first person's estimated degree of interest 331 and an estimation reason 332 therefor. The factors behind the purchase of a product by a customer are determined as a result of generating the estimation model 320 by learning the relationship among person attribute information 321 relating to a second person, product attribute information 322 relating to a second product, line of sight information 333 of the second person in relation to the second product, and the second person's degree of interest 324 in the second product.
