Abstract
A battery condition detection sensor (1) for measuring characteristics of a battery (101) includes an electrically conductive battery post terminal (12) and a shunt resistor (13). The battery post terminal (12) is mounted to a battery post (102) provided in the battery (101). The shunt resistor (13) is electrically connected to the battery post terminal (12). The shunt resistor (13) is configured such that a connection terminal (52) of a wire harness (51) can be fixed thereto. The shunt resistor (13) has a rotation-blocking portion (inner walls of the insertion holes (15a, 15b)) for blocking rotation of the connection terminal (52).
