CURRENT SENSOR AND BATTERY

To provide a current sensor capable of outputting a signal of stable characteristic without being affected by a capacitor, and a battery with the current sensor.SOLUTION: The current sensor comprises: a magnetic detection element detecting magnetism generated by a current flowing in a busbar and having a power supply terminal, a ground terminal and an output terminal from which a desired output signal is output; a large-capacity capacitor having at least a first and a second terminal; and a jumper wire electrically connecting the power supply terminal and the second terminal to each other. The first terminal is electrically conducted to the ground terminal, and the power supply terminal and the second terminal are electrically connected to each other via the jumper wire after the characteristic of the output signal of the magnetic detection element is adjusted.SELECTED DRAWING: Figure 1 【課題】コンデンサに影響されることなく、安定した特性の信号を出力可能な電流センサ、及び当該電流センサを備えるバッテリーを提供する。【解決手段】電流センサは、電源端子、接地端子及び所望の出力信号が出力される出力端子を有し、バスバーを流れる電流により生じる磁気を検出する磁気検出素子と、少なくとも第１の端子及び第２の端子を有する大容量のコンデンサと、前記電源端子及び前記第２の端子を電気的に接続するジャンパー線と、を備え、前記第１の端子は、前記接地端子に導通されており、前記磁気検出素子の前記出力信号の特性が調整された後に、前記電源端子と前記第２の端子とは、前記ジャンパー線を介して電気的に接続されている。【選択図】 図１
