| 摘要 |
An infrared sensor package includes a housing member, which includes an upper-surface section provided with a transmission member which transmits infrared radiation and a lower-surface section and whose inner space is vacuum-sealed, a plate-like heater member which is disposed within the inner space of the housing member and generates heat, an infrared detection element which is fixed onto the heater member and detects the infrared radiation which is transmitted by the transmission member, and a heat-insulating member which has a low thermal conductivity and a smaller cross-sectional area than that of the heater member, and supports the heater member while being fixed onto the lower-surface section.
