摘要

[PROBLEMS] To provide a temperature-sensitive indicator comprising a caps ule filled with a heat-sensitive material, which temperature-sensitive indic ator is not influenced in use by the temperature of a finger and can realize easy breaking of the capsule. [MEANS FOR SOLVING PROBLEMS] The temperature- sensitive indicator comprises a base (2) and a recess part (2a) provided on the base (2). A capsule (3) filled with a heat-sensitive material, an absorb ing member (4) mounted on the upper part of the capsule, and pressing means (6) formed of a transparent heat insulating material disposed on the upper p art of the absorbing member are received within the recess part. A cover (7) is provided so as to cover at least the capsule and the absorbing member. T he capsule (3) is broken by pressing the capsule (3) by the pressing means ( 6).
