<p>In an air conditioner, an indicator panel for indicating its operation status has a half-mirror film formed on its surface so that only a pattern illuminated by a light source provided inside is made visually recognizable. This prevents erroneous recognition of the pattern while improving the appearance. A remote control signal receiver is provided behind the indicator panel so as not to spoil the appearance. An insulating means is provided between the indicator panel and the remote control signal receiver to prevent a short circuit between them. <IMAGE></p>
