To provide a cap having a comb by which the application of a content liquid to hair can be sufficiently and efficiently performed.

On the upper end of an assembling cylinder 5, an erecting cylinder 8 which is flat in the longitudinal direction is erected through an inner flange-shape top wall 7. In this case, the assembling cylinder 5 is closely assembled with a mouth cylindrical section 3 of a container body 2 having squeezing property. Then, a base plate 15 having a comb tooth body 12 wherein a plurality of comb tooth pieces 14 are arranged in two lines with equal intervals for respective lines, is assembled with a recess 11 which is formed on the upper surface of a top plate 9 provided on the upper end of the erecting cylinder 8. On the upper surface of the base plate 15, the comb tooth pieces 14 for the second line are erected and arranged between the comb tooth pieces 14 for the first line by turns in order. In this case, a discharging hole 16 is provided at a right angle to the combing direction of hair, at the upper section of respective comb tooth pieces 14. At the same time, a discharging channel 17 penetrates from the discharging hole 16 to the lower surface of the top plate 9. A fitting cylindrical piece 15a is provided on the lower surface of the base plate 15 in a manner to correspond with the arrangement of respective comb tooth pieces 14. At the same time, a fitting cylindrical section 9a is provided in the recess 11 of the top plate 9. Then, a frame comb tooth piece 13 is erected and arranged at the right and left end sections of the erecting cylinder 8.
