| Zusammenfassung: | An energy converter according to the present invention includes a filament 11 for converting given energy into electromagnetic waves and radiating the waves, and a radiation suppressing portion for suppressing some of the electromagnetic waves (e.g., infrared rays), which have been radiated from the filament 11 and of which the wavelengths exceed a predetermined value. The radiation suppressing portion has a bundle 12 of fine wires 12 a, of which the axial direction is aligned with a direction in which the electromagnetic waves propagate with their radiations suppressed. |
