A wireless communication device of the present disclosure, to which an electric power measurement value is input that is measured in an electric power measurer to which a power supply side power line and a load side power line are connected, includes a first antenna element that transmits and receives radio waves and a wireless circuit connected to the first antenna element. The first antenna element has a longitudinal side perpendicular to a line along which the power supply side power line and the load side power line extend.

Wireless communication device

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.

To provide a portable terminal which can detect the using modes of the portable terminal, can reduce the number of members necessary for detecting the using modes and further can reduce leakage magnetic force badly influencing on other devices. A portable terminalincludes a first casingand a second casinghaving inner side surfacescapable of opposing to each other, respectively, and a hingefor coupling the first casingand the first casing. The first casingis provided with magnetic materialsand the casingis provided with magnetic sensorsfor detecting the magnetic materials, respectively. The magnetic sensorsand the magnetic materialsdetect the using modes including a folded state or a bent state of the first casingand the casing
