First, second, and third bottom stepped portions 18, 20, 22 are formed stepwise at a lead end portion of a casing 10 of a liquid applicator. First, second, third, and fourth lead stepped portions 32, 34, 36, 38 are formed stepwise at a bottom end portion of a lead portion 12 of the liquid applicator. Lead end faces 24, 26 of the second and third bottom stepped portions 20, 22 are adhered with bottom end faces 40, 42 of the second and third lead stepped portions 34, 36 by means of an ultrasonic adhesion in a state where the respective bottom stepped portions are brought into contact with the corresponding lead stepped portions. Accordingly, the adhered faces are prevented from coming apart at each adhered portion in the liquid applicator including lead and bottom side shafts which are coupled with each other by means of ultrasonic adhesion.
