PROBLEM TO BE SOLVED: To provide a liquid supply implement, capable of easily confirming the suitable supply of a liquid. SOLUTION: The liquid supply implement comprises a body (1) as a transparent cylindrical body having a nozzle (2) provided at a distal end, and a presser (3) disposed at the inside of the body to press a liquid by sliding in a major axis direction of the body. In the implement, the slight slide of the presser can be easily confirmed by visually observing the body (1) via interference fringes of line groups (5, 6) respectively provided on the surfaces of the body (1) and the presser (3). |
