Ground connection structure

A ground connection structure, comprising:

• a plurality of grounding wires being respectively connected to a plurality of electrical components installed in a vehicle;
• a connected part to which the grounding wires are electrically interconnected;
• a grounding terminal part connected to a body of the vehicle in an electrically conducting state;
• and
• an electrically conducting connection part having one end in and connected to the connected part and the other end connected to the grounding terminal part to connect the connected part and the grounding terminal part in an electrically conducting manner, wherein
• the electrically conducting connection part is made of a low-inductance material having lower inductance than a single-core circular wire having a diameter established by current capacities of the plurality of grounding wires,
• the connected part is arranged between the grounding wires and the electrically conducting connection part;
• the connected part is a connection box into which one end of the electrically conducting connection part and one end of each of the plurality of grounding wires are inserted,
• the one end of the electrically conducting connection part is welded via a first weld to a first portion on an inside of the connection box, and
• the one end of each of the plurality of grounding wires is welded via a second weld to a second portion on the inside of the connection box.
