Claim:
1. A wireless communication module comprising: an antenna configured to be disposed on a first conductive wall among a plurality of the conductive walls enclosing a closed space; a tag reader configured to be connected with the antenna, and to read an RFID tag existing in the closed space via the antenna; and a reflective part configured to have a thin film shape or a plate shape, and to be disposed between the first conductive wall and a second conductive wall facing the first conductive wall, wherein the closed space is partitioned by the reflective part into a first space on a side of the first conductive wall and a second space on a side of the second conductive wall, wherein a radio wave is output by the tag reader, radiated from the antenna, and reflected by the reflective part, to become a first reflected wave propagating in the first space, wherein the radio wave radiated from the antenna also transmits through the reflective part, propagates in the second space, is reflected by the second conductive wall, and transmits through the reflective part, to become a second reflected wave propagating in the first space, wherein a position of the reflective part between the first conductive wall and the second conductive wall is determined so that the first reflected wave and the second reflected wave are canceled by each other.
