A traffic monitoring device includes an identification unit that identifies a flow of a packet received from a monitoring target network into a flow of a first flow group and a second flow group other than the first flow group on the basis of a rule table in which a predetermined rule is registered, a traffic aggregation unit that aggregates a traffic amount of the first flow group for each flow, an occurrence probability calculation unit that calculates an occurrence probability of each flow on the basis of a result of sampling at least some of the flow of the packet received, and a traffic estimation unit that estimates a traffic amount of each flow of the second flow group by multiplying the occurrence probability of each flow by the total value of the traffic amount of the second flow group.
