Document Type and Number:
WIPO Patent Application WO/2019/159549
Kind Code:
A1
Abstract:
This circuit board is provided with a prescribed circuit unit that generates heat and electromagnetic noise, and is fixed to a conductive casing by a conductive screw. The circuit board has: an insulator layer that includes an insulative plate-like base material; a conductor layer that has a circuit pattern including a ground part and that is disposed on at least one surface of the insulator layer; and a screw insertion hole which penetrates the insulator layer and the ground part and through which the screw is inserted. The ground part has a slit that is disposed between the screw insertion hole and the prescribed circuit unit. The ground part has a ground bridge that electrically connects a portion of the ground part between the slit and the screw insertion hole and a portion of the ground part between the slit and the prescribed circuit unit.
