Infrared sensor package and electronic device equipped therewith

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.

1. An infrared sensor package comprising:
a housing member comprising an upper-surface section provided with a transmission member which transmits infrared radiation and a lower-surface section, wherein inner space of the housing member is vacuum-sealed; a plate-like heater member which is disposed within the inner space of said housing member and generates heat; an infrared detection element which is fixed onto a center area of said heater member and detects the infrared radiation which is transmitted by said transmission member; and a heat-insulating member which has a low thermal conductivity and a smaller cross-sectional area than that of said heater member, and supports said heater member while being fixed onto said lower-surface section, wherein said heater member is fastened on said lower-surface section of said housing member via said heat-insulating member, and said heat-insulating member is made of glass, and wherein said heat-insulating member is fastened onto edge areas of said lower-surface section, where said heat-insulating member stably supports said heater member.
