PURPOSE:To prevent the outflow of heat and to reduce measuring errors by providing a heat insulating and electric conductor layer. CONSTITUTION:The 1st good electric conductor layer 1, an endothermic heating body layer 2, a heat insulating and electric conductor layer 3 and the 2nd good electric conductor layer 4 are laminated from the inflow side for energy. The layer 1 consists of a film-like good electric conductor of about 0.1mum thickness. The layer 2 is a layer of about 100mum thickness consisting of a material which heats up by absorbing the electric charge particles passing through the layer 1. The layer 3 is a layer of about 100mum thickness consisting of a material which shuts off heat and has electric conductivity. The layer 4 consists of the same material as that of the layer 1. An electric current terminal 5 and a voltage terminal 6 are connected to the layer 1, and the layer 4 is grounded. |
