PROBLEM TO BE SOLVED: To provide a wiring breaker type electronic watt-hour meter, having a low priced (reduction in man-hours and in material cost) and reliable connection structure that can easily connect to a terminal and a common voltage circuit, without enlarging instrument dimensions. SOLUTION: The electronic watt-hour meter 1 comprises the terminal parts of a power source sides 21aS, 21bS, 21cS connected to a power source, the terminal parts of a load side 21aL, 21bL, 21cL connected to a load, an instrument current wire connecting the terminal part of the power source side 21aS and the terminal part of the load side 21aL, and a voltage wire 35a connecting either of the terminal parts, in which the voltage wire 35a mounted on a printed wiring board 52, where an electronic circuit is installed, is sandwiched between the instrument current wire 30a and a terminal nut 16 provided on the terminal part 21aS, to be fixed there. |
