    Abstract: Provided is a plug device which includes: a body portion; and a valve element portion. A fluid flow passage is formed in the body portion. The fluid flow passage extends along an axis, and has a valve hole at one end thereof. The valve element portion is accommodated in the body portion in an advancing and retracting manner along the axis. A proximal end portion of the valve element portion is made of a conductive fluororesin material containing a fluororesin material and carbon nanotubes dispersed in the fluororesin material. The proximal end portion is conductive with a conductive member maintained at a ground potential. A volume resistivity of the conductive fluororesin material falls within a range of larger than 1.0x×103 Ω·cm and less than 1.0×104 Ω·cm.

    Abstract: Provided is a flow meter that determines a liquid flow rate based on temperature. The flow meter has a cylindrical measurement tube having an internal flow passage, and a temperature detecting substrate including a heating resistance element a temperature detecting resistance element formed on a detection surface thereof. The measurement tube has a flat surface facing the detection surface of the temperature detecting substrate, and a pair of recesses arranged so as to sandwich the internal flow passage at a position where the heating resistance element is arranged. The flat surface and the detection surface are bonded together to form two bonding area. A width of the first bonding area is narrower than a width of the second bonding area so that heat, transmitted through the measurement tube from the heating resistance element is increased.
