The present invention relates to a pumping-type cosmetic container having a side button, and, when pressing a button part which is positioned toward a side so as to be crossed at a right angle to a container body, a first check valve is closed while a second check valve is opened, and the contents flowing into a cylinder are discharged outward through an applicator. Therefore, with a simple structure of the pumping-type cosmetic container having a side button, a user can directly apply a fixed amount of contents to a desired region.
