1. A method for manufacturing an evaporator for ice-making, the method comprising:
a preparation operation of preparing a plate member provided with a plurality of through-holes formed therein, and further providing a plurality of finger members and a capillary tube;
an insertion operation of inserting each of the finger members into the through-holes such that at least a portion of each of the finger members penetrates through the through-holes;
a connection operation of fixedly connecting the finger members to the plate member;
an insert placement operation of placing at least a portion of the capillary tube on the plate member; and
an evaporation tube forming operation of bending the plate member in a form of a pipe and connecting end portions of the plate member to form an evaporation tube in which a refrigerant flow path, through which a refrigerant flows, is formed.
