In an injection-molded hearing aid-type eyeglass temple which includes a straight temple portion having a first cavity and an adjoining, inclined free end portion having a second cavity, there is provided a thin-walled tube embedded in a solid temple portion. The throughgoing longitudinal passage in the tube constitutes a connecting channel which maintains communication between the two cavities and through which extend electric conductors for interconnecting the hearing aid components accommodated in the two cavities.
