A transfer module (2, 3) for transferring transmission target information on a predetermined transfer path including an information processing apparatus, the transmission target information being information to be processed by the information processing apparatus or information that has been processed by the information processing apparatus, the transfer module (2, 3) comprising: a reception unit configured to receive predetermined transmission information including the transmission target information from an upstream transfer module located upstream from the transfer module (2, 3) on the predetermined transfer path; a transfer environment information obtaining unit configured to obtain transfer environment information indicating a degree of influence placed by the transfer module (2, 3) on an information transfer result of the transmission target information transferred to the information processing apparatus or an information transfer result of the transmission target information transferred from the information processing apparatus, the transfer environment information including at least one of module internal information or module surrounding information, the module internal information being information about a transfer environment for the transmission target information in the transfer module, the module surrounding information being information about a transfer environment associated with a surrounding of the transfer module excluding the upstream transfer module; a generation unit configured to append the transfer environment information obtained by the transfer environment information obtaining unit to the predetermined transmission information received by the reception unit to generate new predetermined transmission information; and a transmission unit configured to transmit the new predetermined transmission information generated by the generation unit to a downstream transfer module (2, 3) located downstream from the transfer module (2, 3) on the predetermined transfer path, characterized by that the generation unit determines whether transfer environment of the predetermined transfer path degrades or not based on the transfer environment information obtained by the transfer environment information obtaining unit or in accordance with a change history of the transfer environment information obtained by the transfer environment information obtaining unit, and wherein the generation unit lowers a frequency of appending the transfer environment information to the predetermined transmission information received by the reception unit in case that it is determined that the transfer environment of the predetermined transfer path does not degrade. a reception unit configured to receive predetermined transmission information including the transmission target information from an upstream transfer module located upstream from the transfer module (2, 3) on the predetermined transfer path;
