To provide a temperature-sensitive indicator which, when using the temperature-sensitive indicator having a capsule packed with a heat-sensitive material, enables easy rupture of the capsule, without being affected by the temperature of a finger of a user. The indicator includes: a base; a concave portion formed in the base; a capsule accommodated in the concave portion and packed with a heat-sensitive material; an absorbing member placed on the capsule; pressing means which is arranged above the absorbing member, and which is formed of a transparent heat insulating material; and a cover which covers at least the capsule and the absorbing member. By pressing on the capsule using the pressing means6,the capsule is ruptured.
