Abstract
An oven observing equipment capable of observing the inside of an oven turned to a high temperature precisely includes: a housing 13 having an intake part for cooling air, and a discharging part for discharging the cooling air after being used for cooling; and an imaging device 20 contained in this housing 13 near the discharge part. This imaging device 20 is composed of integrated combination of an image sensor 16; plate-like thermoelectric cooling elements 18a to 18d arranged in a state that their heat-absorbing faces surround the periphery of a body of the image sensor; thermoconductive blocks 17a to 17d embedded in the gaps between the image sensor body and the thermoelectric cooling elements 18a to 18d; and cooling fins 19a to 19d formed on the heat-radiating faces of the thermoelectric cooling elements 18a to 18d are integrated with each other.
