<P>PROBLEM TO BE SOLVED: To provide an infrared sensor which: has compact, thin and simple element geometry; and stably detects temperature of a measurement object even with temperature disturbance caused by external thermal emission (radiation) as well as thermal emission from a heat sensitive element and with temperature distribution at an installation location of a sensor element. <P>SOLUTION: An infrared sensor comprises: a light receiving surface which receives infrared; a sensor element which detects the infrared and outputs an electric signal; a connection terminal to transmit the output of the sensor element to an external device; connection wiring which electrically connects the sensor element and the connection terminal; and a sealing member which seals the sensor element together with the connection terminal as well as the connection wiring except an opening for a light receiving surface. The sealing member has a holding section which holds the sensor element and a field angle restriction section which is extended from the holding section so as to surround a periphery of the light receiving surface and thereby restricting a field range with respect to the infrared incident on the light receiving surface. An outer periphery of the light receiving surface is covered by the field angle restriction section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
