A flat wiring structure is including a plurality of layers, and includes a power supply layer, and a first ground layer and a second ground layer laminated with the power supply layer sandwiched therebetween. In a plan view of the flat wiring structure when viewed from a direction along a lamination direction of the first ground layer, the power supply layer, and the second ground layer, the power supply layer has a width in a short direction smaller than those of the first ground layer and the second ground layer, and the power supply layer is provided at a position covered with the first ground layer and the second ground layer.

A shunt resistance type current sensor includes a bus bar, a circuit board disposed to oppose the bus bar, a shunt resistance part in the bus bar, connection terminals which electrically connect the bus bar and the circuit board, and a voltage detector which is mounted on the circuit board and detects a voltage applied to the bus bar to detect a magnitude of current to be measured flowing through the bus bar. The connection terminal is formed integrally with the bus bar as an extending piece extended from an edge part of the bus bar, an area of the connection terminal reduced in its plate thickness than that of the bus bar is set in a range from a tip side thereof, and the tip side of the connection terminal penetrates the circuit board and connects with the circuit board.
