PROBLEM TO BE SOLVED: To provide a current measuring device with improved current measuring accuracy for restraining influences on temperature change of a cell by inserting the current measuring device.SOLUTION: A current measuring device 1 comprises: a plate-like member 2; plural split electrode parts 3 including a first electrode part 3a provided on one face of the plate-like member 2 and a second electrode part provided on the other face; a conduction part 5 electrically connecting the first electrode part 3a and the second electrode part and having a resistor 4 with a predetermined resistance value; and a control part as measurement means for measuring a value of a current flowing through the electrode part 3 based on the resistance value of the resistor 4 and a potential difference between two points of the resistor 4. In the current measuring device 1, the plate-like member 2 is arranged between a pair of cells 10 adjacent to a fuel battery constituted by laminating the cells 10, so as to measure the value of the current flowing in local parts of the cells 10. Then, the plate-like member 2 has at least one hollow part 9 near the resistor 4. |
