PROBLEM TO BE SOLVED: To provide an oil container allowing essential oils and the like to be continuously and sufficiently vaporized, and to provide an easy-to-use aroma diffuser capable of wafting aromas into a space with a relatively simple structure.SOLUTION: An oil container 1 has a container body 10, a core material 11, an absorber 12, and a lid portion 13. The outer shape of the absorber 12 is formed larger than the cylinder diameter of the container body 10. The lid portion 13 includes a lid body 131 holding the core material 11, and a holding portion 132 projecting outward from an outer peripheral surface of the container body 10 and holding the absorber 12 in a state where its surface is exposed to the outside. An aroma diffuser 2 includes a first space portion 21, and a second space portion 22, a blower fan 25, and a discharge port 26. Air sucked from an outside air suction port 222 into the second space section 22 is sent to the first space portion 21 through a hole portion 210b by the blower fan 25. Essential oils 102 vaporized from the absorber 12 by air blowing is discharged outside from the discharge port 26.SELECTED DRAWING: Figure 8
