Abstract: A temperature measurement apparatus includes a first temperature sensor disposed so as to be close to a contact surface with an object to be measured in a thickness direction of an apparatus main body, and a second temperature sensor disposed so as to be close to a display unit in the thickness direction of the apparatus main body. The display unit is switched between a first display state and a second display state by switching a mark between display and non-display. An internal temperature of the object to be measured is calculated by using a detected temperature in the first temperature sensor and a detected temperature in the second temperature sensor in the first display state, and a detected temperature in the first temperature sensor and a detected temperature in the second temperature sensor in the second display state.
