PROBLEM TO BE SOLVED: To provide a battery state detection sensor device securing long-term electric connection reliability by removing generation of a stress load in a connection part of a shunt resistor and a connection part of an electronic control substrate for connecting electrically a connection conductor, and a risk of breakage of the connection conductor, during assembling for connecting the shunt resistor to the electronic control substrate through the connection conductor and arranging them in a protection case. SOLUTION: This device includes: super-elastic alloy lead wires 21, 22 slackened and arranged between the electric connection part of the shunt resistor and the electric connection part of the electronic control substrate, in the state where the electric connection parts 11S, 12T of the shunt resistor 4 is electrically connected to the electric connection parts 5S, 5T of the electronic control substrate 5; and the protection case 90 in which the electronic control substrate and the connection conductor are sealed by a resin mold material heat-cured by filling the resin mold material, in the state where the shunt resistor is held and the electronic control substrate and the connection conductor are stored.
