    • A light-emitting device according to the present invention includes: first insulators (4) arranged so as to face each other; an emitter (2) arranged between the first insulators; a second insulator (5) functioning as a base for the first insulators and the emitter; an electrode (6) arranged to face, or contact with, the first insulators partially; another electrode (10) contacting with the second insulator and interposing the second insulator between the electrode and itself; and a light-transmitting substrate (8) that faces the second insulator with the first insulators interposed somewhere and with the emitter interposed elsewhere. If the first insulators are extended to reach the light-transmitting substrate on a cross section including the first and second insulators, the emitter and the light-transmitting substrate, the ratio of the cross-sectional area of the emitter to the combined cross-sectional area of the first and second insulators and the light-transmitting substrate is defined so as to fall within a predetermined range.

    • A wire electric discharge machine capable of preventing a straightness error from being caused by consumption of a wire electrode, to eliminate insufficient machining. A correction angle φ is predetermined for preventing the straightness error of the workpiece due to consumption. Correction amounts d1′, d2′ on a program plane and an upper surface of a workpiece, respectively, are determined based on the predetermined correction angle φ, and are added to or substracted from a predetermined offset amount depending on a wire electrode radius and an electric discharging gap, to determine corrected offset amounts d1, d2 on the program plane and the upper surface of the workpiece, respectively. Correction amounts dlo, dup for lower and upper wire guides in an offset direction are obtained based on the corrected offset amounts d1, d2, respectively, so that motion paths of upper and lower wire guides relative to the workpiece are determined.
