In a skin needle manufacturing apparatus 10, a materialmelted in a syringe 45 is discharged from a fine hole 47a ofa pin member 47 and is caused to adhere to a base 48. A computer50 causes a drive mechanism 48 to separate the pin member 47from the base 48. Then, the material 80 having adhered to thepin member 47 and the base 48 is drawn out. A projection portion48b formed of a part of the material 80, which has adhered tothe base 48, is formed into a skin needle 81. Consequently,a skin needle can relatively easily be manufactured withoutrequiring excessive time, effort, and cost.
