The operation support apparatus includes: an operation load calculation unit (106) which calculates an operation load on a user in performing a selecting operation included in one of operation records, using the selecting operation and a previous selecting operation included in another one of the records, the calculation being performed for each of selecting operations included in the records; a non-thinking operation determination unit (107) which determines, for each selecting operation included in the records, whether or not it is a non-thinking operation that is a randomly-performed operation, by determining that the selecting operation is more likely to be the non-thinking operation when the operation load is smaller; and a target function inference unit (108) and a target function candidate storage unit (109) which provide the user with operation support based on the records of the selecting operations excluding the selecting operation determined as the non-thinking operation.
