PROBLEM TO BE SOLVED: To provide an eyedropper which can always surely make a fixed quantity of liquid to drop down when its main body is pressed without detracting the advantage in manufacturing cost of its bottle pack type main body. SOLUTION: At the front end section of the main body A of an eyedropper in which a liquid is simultaneously packed in a hermetically sealed state when the main body A is molded and which is made of a thermoplastic material, a bottomed conical recessed section 6b having an inside diameter which becomes larger as going toward the front end side is formed. In addition, a small- diameter liquid injection hole 6c is formed through the bottom of the recessed section 6b so as to control the quantity of a droplet squeezed out of the main body A to a set value.
