PROBLEM TO BE SOLVED: To provide a transmitter-receiver in which a substrate provided with a control part and a battery 3 for supplying electric power to the control part are included and a resin is injection molded to peripheral areas of the substrate and the battery.SOLUTION: A transmitter-receiver includes a substrate 2 provided with a control part and a battery 3 for supplying electric power to the control part. The entire battery 3 is covered by a covering material 6, and the entire substrate 2 and the entire covering material 6 are covered by a coating material 22. The coating material 22 is integrally formed by injection molding a resin to outer peripheries of the substrate 2 and the covering material 6. The covering material 6 decreases a temperature applied to the battery 3 during injection molding. |
