PROBLEM TO BE SOLVED: To provide a linear pump reduced in size over the whole of the pump by simplifying the structure of the linear pump. SOLUTION: This linear pump includes: a body part including a storage part storing a solution to be distributed, a flow-in route through which the solution flows into the storage part, a flow-out route through which the solution flows out of the storage part, and a valve space formed over the flow-in roue and the flow-out route; a piston to be inserted into the storage part of the body part freely to be elevated; a valve rotatably provided in the valve space of the body part and formed with a first route connected to the flow-in route and a second route connected to the flow-out route so as to respectively open/close the flow-in route and the flow-out route based on a rotating angle; and a pump body including a pump shaft connected to the piston, an elevating means for elevating the pump shaft, and a valve operating means for rotating the valve.
