PROBLEM TO BE SOLVED: To make a pumping volume zero, to reduce a device in size and cost, and to facilitate control. SOLUTION: This slide-type solenoid valve comprises a fluid channel constituting member 2, a fluid channel constituting member 3, and a slide seal plate 9 which is arranged between the fluid channel constituting member 2 and the fluid channel constituting member 3 so as to be slidable with respect to the fluid channel constituting members 2, 3. The slide seal plate 9 comprises fluid channel blocking walls 26, 27 which can block a fluid channel opening hole 25 communicable with fluid channels 5, 6 and 7, and the fluid channels 5, 6 and 7. The solenoid valve also comprises a spring 20 which constantly generates a force which keeps the slide seal plate 9 in an original point position, and a solenoid 14 which makes the slide seal plate 9 slide form the original point position while withstanding the force of the spring 20 at the application of electricity. The slide seal plate 9 switches the fluid channels 5, 6 and 7 by using the fluid channel opening hole 25 and the fluid channel blocking walls 26, 27 in accordance with the presence or absence of the application of electricity to the solenoid 14.
