Infrared sensor package and electronic device equipped therewith

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.
