Abstract
An electrical connection structure of an electronic board includes: a board support member formed of synthetic resin; an electronic board fixed to the board support member; an electrical connection pad disposed on the electronic board; a bus bar disposed in the board support member; and a bonding wire that electrically connects the electrical connection pad and the bus bar. The bus bar includes: an exposed portion exposed in a face of the board support member; an embedded portion embedded in the board support member; and a connection portion extending from the exposed portion and being electrically connected to an electrical component. An end of the bonding wire is bonded to the exposed portion, and a first cut portion is formed in the embedded portion.
