Abstract
A wireless communication device includes: flow-rate measuring unit connected to fluid pipe; and first antenna element that transmits and receives a radio wave. First antenna element has a longer side orthogonal to an axis of fluid pipe. According to this configuration, a direction of a plane of polarization of a radio wave radiated from first antenna element is orthogonal to fluid pipe. Thus, the radio wave is not reflected by fluid pipe but propagates in a direction toward fluid pipe, namely, in a rear surface direction of a meter including the wireless communication device.
