<p>PROBLEM TO BE SOLVED: To provide a manufacturing method of a temperature sensor having a resin molded thermistor element capable of enhancing airtightness to the thermistor element in the temperature sensor.SOLUTION: The temperature sensor includes: a sensor unit 4 having a thermistor element 1 connected to a connection terminal 2 with lead wires 3; and a resin mold section 8 covering the same. The resin mold section 8 is formed through: a primary molding step to form an outer resin mold member 10 which has an opening 10a for inserting the sensor unit 4 from the thermistor element 1 side; and a secondary molding step to form an inner resin mold member 11 by filling the opening 10a with a molten resin after inserting the sensor unit 4 into the opening 10a.</p> |
