A method and apparatus of measuring the temperature of the core of a body wherein, the apparatus is comprising: a capsule (10), the inside of which is heat conductive, which has a surface adapted to be placed in contact with the surface of the body the core temperature of which is to be measured, and which is thermally insulated on all its surfaces; a heating element (11) for heating the inside of the capsule; two temperature sensors (12) and (19) for measuring the temperature of two points inside the capsule and the difference of said temperatures; a control module (14), including a power supply (15), and a connection (18) between the capsule and the control module. The method is comprising: a) providing a heat conductive space outside the body and in contact with its surface; b) monitoring the difference of the temperatures of two points located within said space and at different distances from said body surface; c) if said temperature difference indicates that heat is flowing from the body surface outwards, generating heat in said space, whereby to reduce said temperature difference; d) monitoring said temperature difference, and e) assuming the temperature of one of said two points, when said temperature difference is zero, as the temperature of body core.
