An electric connection block is provided with a bus bar formed from a press-formed product of a metal plate member and a resin-made housing insert molded integrally with the bus bar. The bus bar is provided with a flat plate-shaped main plate part and a standing terminal erected by bending a base end connected to a portion of the main plate part relative to the main plate part. The electric connection block is manufactured by insert molding the housing integrally with the bus bar in a before-bending state where the standing terminal is located on the same plane as the main plate part, and bending the base end of the standing terminal to thereby erect the standing terminal relative to the main plate part after the insert molding of the housing.
