RESISTANCE ADJUSTING METHOD OF INFRARED-RAY DETECTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To enhance productivity of an infrared-ray detecting element by readily reducing the difference between the resistance of the infrared-ray detecting element and the specified resistance. SOLUTION: This is a resistance adjusting method of an infrared-ray detecting element, which has a thermistor film 12 formed on a substrate 11, and a pair of electrodes 13a and 13b which are formed on the thirmistor 12 and formed in a comb shape so as to be engaged to each other with the specified space being provided. A pair of the electrodes 13a and 13b are formed so that the resistance between the pair of the electrodes 13a and 13b becomes the specified value or less. Thereafter, a part of the comb of any one electrode of these electrodes is cut by laser or a diamond. Thus the resistance between the pair of the electrodes are adjusted to the specified resistance.
