Provided are a cap and a droplet discharge device that prevent clogging of a liquid discharge port. A cap having at least an inner wall provided with a humidity control material made of an inorganic porous material, and a droplet discharge device including the cap for sealing a droplet discharge port for discharging droplets by an inkjet method. is there. In addition, by connecting the waste ink tank and the cap 102 and supplying moisture in the waste ink tank into the cap, the humidity in the cap can be stabilized in a higher state.
