Claims (14)

1 . A coating device comprising:

a backup roll configured to transport a workpiece;

a coating die configured to discharge a coating liquid onto the workpiece;

a drive section configured to drive the backup roll; and

a heat dissipation section configured to dissipate heat generated in the drive section,

wherein the drive section includes a speed reduction section coupled to the backup roll, and a drive motor that is configured to input drive force to the speed reduction section; and

wherein a portion of the heat dissipation section is interposed between the speed reduction section and the drive motor.

2 . The coating device of claim 1 , further comprising a thermal insulation section disposed between the backup roll and the drive section.

3 . The coating device of claim 2 , further comprising:

a support section configured to support the backup roll,

wherein the thermal insulation section is interposed between the support section and the drive section.

4 . The coating device of claim 1 , wherein:

the heat dissipation section includes an interpose section interposed between the speed reduction section and the drive motor; and
