<p>PROBLEM TO BE SOLVED: To provide a seal failure inspection device and a seal failure inspection method capable of discriminating whether contents are contained in an outer package or not without requiring strict management of product weight, at a low cost and without making it a condition that metal is contained only in the contents.SOLUTION: A content detection device 100 is used in a manufacturing line of a packaged article 200 made by including first contents 210 and second contents 220 in an outer package 231. Therein, the second contents 220 before being included in the outer package 231 are preliminarily heated or cooled and a temperature of the outer package 231 after passing through a process in which the second contents 220 are included in the outer package 231 is detected by a temperature sensor 120 from an outer part. In the content detection device 100, whether the second contents 220 is included in the outer package 231 or not is discriminated based on the detected temperature.</p> |
