摘要： A moisture measuring device includes a biosensor, a processing unit, a substrate, a housing, and one or more attaching members. The biosensor has a sensor surface for acquisition of biological information. The processing unit is configured to process the biological information acquired by the biosensor. The substrate has a first principal surface on which the processing unit is mounted. The housing accommodates the biosensor, the processing unit, and the substrate. The one or more attaching members are disposed on the first principal surface side of the substrate to attach the substrate to the housing. The total area of one or more overlap regions in which the one or more attaching members overlap the substrate in the first principal surface of the substrate when viewed in a direction perpendicular to the first principal surface of the substrate is smaller than a sensor area of the sensor surface of the biosensor.

摘要： A measuring device is provided for reducing the occurrence of damage to a sensor section. The sensor section includes a substrate, a pair of comb electrodes on a first principal surface, and a pair of back-side electrodes disposed on a second principal surface and corresponding to the pair of comb electrodes, respectively. The pair of comb electrodes includes a plurality of tooth sections and connection sections that connect the tooth sections to each other, respectively. The substrate includes via-hole conductors in positions corresponding to the tooth sections inside a region surrounded by the outer tooth sections on opposite ends in a direction in which the tooth sections in the pair of comb electrodes are aligned and the connection sections. The via-hole conductors connect the comb electrodes and the back-side electrodes.
