The present invention addresses the problem of providing a temperature sensing body capable of sensing both a temperature increase and a temperature decrease, and having an anti-tampering function. In order to solve said problem, this temperature sensing body is characterized by including: a first ink in which a temperature Ta1 for initiating color disappearance when the temperature rises and a temperature Td1 for initiating color development when the temperature falls are different; and a second ink in which a temperature Ta2 for initiating color disappearance when the temperature rises and a temperature Td2 for initiating color development when the temperature falls are different, wherein the temperature Ta1 for initiating color disappearance, the temperature Td1 for initiating color development, the temperature Ta2 for initiating color disappearance, and the temperature Td2 for initiating color development have the relationship, Td1
