Document Type and Number:

Japanese Patent JP3716249

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a heating device capable of improving the accuracy of temperature measurement at a heater plate made of aluminum.
SOLUTION: The heating device 11 comprises a heater plate 13 made of aluminum having a heating element 12 and a sheathed thermocouple 14 for measuring the temperature of the heater plate 13. The tip 26 of the sheath 25 made of aluminum is closed by the end of a wall 30, and the end surface 26a of the tip 26 is finished flat by machining. The heater plate 13 is composed of a first plate member 21 and a second plate member 22. A sheath mounting hole 40 is formed in the first plate member 21.
