A cost-effective electronic thermometer comprises a rigid case attached to a flexible probe stem in a lap joint. The distal end portion of the relatively rigid case is affixed to the flexible probe stem at the lap joint by a molding weld between the case and the flexible probe. A substantially rigid insert is positioned partially within an axially extending passageway defined by the stem such that a sensor cap can be mounted around the insert. A temperature sensor in sensor cap is connected to an electronic processor with display that is positioned within case and powered by a battery.
