A Flow Record restriction apparatus is provided for restricting a transmission number of Flow Records while maintaining measurement information of the whole traffic. The Flow Record restriction apparatus includes: a flow generation unit 202 configured to determine a set of packets having the same attribute to be a flow of the same communication, and to generate a Flow Record based on header information of the packets for each flow; a Flow Record number restriction function unit 203 including a management buffer for temporarily storing generated Flow Records, and being configured to read the Flow Records from the management buffer and output the Flow Records; and a Flow Record transmission unit 204 configured to packetize the output Flow Records to transmit packets over the measurement network, wherein, when a number of Flow Records stored in the management buffer exceeds a preset upper limit value, the Flow Record number restriction function unit 203 aggregates a part of stored Flow Records.
