ABSTRACT:
A meter device in which a casing having a front opening portion and a back opening portion is provided therein with a partition wall to form a front-side containing space and a back-side containing space, an electric meter main body is contained fixedly in the front-side containing space, and a circuit board is attached to the back opening portion side of the casing, with the electronic part mounting side directed toward the partition wall, whereby an electronic part mounted on the circuit board is contained in the back-side containing space. The meter device facilitates assembling operations and electrically connecting operations. With the electronic part containing space partitioned into a plurality of containing spaces, the electronic part which generates heat can be isolated from the other electronic parts, whereby thermal interference is reduced.
