Abstract
A temperature sensing indicator provided with a capsule having a temperature sensing material contained that can be used without being affected by the temperature of fingers and allows the capsule to be easily broken. The temperature sensing indicator irreversibly indicates that a sensed temperature is not lower than a predetermined temperature or not higher than the predetermined temperature when a capsule containing a temperature sensing material is broken. The temperature sensing indicator has a body base made of a plastic material having a recess section formed therein; the capsule contained in the recess and containing the temperature sensing material, an absorbing member mounted on the upper part of the recess, and in which a through hole that exposes a portion of the upper surface of the absorbing member is formed. Pressing the display label crushes the recess in the body base to break the capsule.
