To provide an electronic watthour meter that allows a sensor that communicates with an infrared communication port to be stably fixed to a meter, during inspection work or the like of the meter.SOLUTION: An electronic watthour meter equipped with an infrared communication port capable of communicating with an infrared sensor device includes: a watthour meter body equipped with a housing with a built-in electronic component; a sealing cover for sealing the front of the housing; and fixing means capable of fixing the infrared sensor device to the electronic watthour meter. The fixing means includes a protrusion provided on the front of the sealing cover. The protrusion has an engaging portion that can engage with a part of the infrared sensor device. This allows the infrared sensor device to be supported at a position where the infrared sensor device can communicate with the infrared communication port.SELECTED DRAWING: Figure 7 【課題】計器の点検作業等の間、赤外線通信ポートと通信するセンサを計器に安定して固定しておくことができる、電子式電力量計を提供する。【解決手段】赤外線センサ装置と通信可能な赤外線通信ポートを備える電子式電力量計であって、電子部品が内蔵される筐体を備える電力量計本体と、筐体の前面を封印するための封印カバーと、赤外線センサ装置を電子式電力量計に固定可能な固定手段と、を備えており、固定手段は、封印カバーの前面に設けられる突起部を含み、突起部は、赤外線センサ装置の一部と係合可能な係合部を有し、これにより、赤外線センサ装置が赤外線通信ポートと通信可能な位置に、赤外線センサ装置を支持可能である、電子式電力量計。【選択図】図７
