Disposable electronic thermometer

A disposable electronic thermometer comprising:

• a base substrate including an adhesive layer formed on one surface, the adhesive layer configured to be attached to a user's body;
• a controller including a circuit board disposed on one surface of the base substrate and at least one driving chip mounted on the circuit board;
• a temperature sensor disposed on one surface of the base substrate and electrically connected to the circuit board, the temperature sensor configured to measure the user's body temperature;
• a Near Field Communication (NFC) antenna electrically connected to the circuit board and disposed on one surface of the base substrate;
• and
• a cover member attached to one surface of the base substrate to prevent external exposure of the circuit board, the temperature sensor and the NFC antenna,
• wherein the base substrate includes a plate-shaped first portion in which the circuit board and the NFC antenna are disposed, and a second portion formed in a bar shape and extending lengthwise from the first portion, the second portion having a smaller area than the first portion and having the temperature sensor disposed on the second portion,
• wherein the NFC antenna is a separate wire-wound coil member disposed on the one surface of the base substrate, is configured as a coil in which a wire having a predetermined length is wound multiple times, and is disposed on the first portion to surround an outside of the circuit board, wherein the NFC antenna is not an antenna pattern formed on the circuit board, and both ends of the NFC antenna are electrically connected to the circuit board,
• wherein among the at least one driving chip, the NFC antenna, and the temperature sensor, only the at least one driving chip is mounted on the circuit board, and neither the NFC antenna nor the temperature sensor is mounted on the circuit board, and the circuit board is disposed in an inner region of the NFC antenna without an antenna pattern formed thereon so as to occupy only a partial area of the first portion, and
• wherein the temperature sensor is disposed at an end portion of the second portion and is electrically connected to the circuit board through at least one wire extending from the circuit board to the second portion, wherein the at least one wire extends along the second portion to the temperature sensor, and the temperature sensor is not mounted on the circuit board.
