To provide a spoon that can spoon up a substance without any fatigue by developing resistance to the spoon regardless of physical characteristics in a granular substance.
The spoon has a handle that is interlocked to a back wall and a nearly flat front wall that opposes the handle, and is improved based on human engineering. A spoon volume section is demarcated between the front and back walls. The spoon volume section has a spoon opening section that is surrounded by the front and back walls, and at the same time the ratio of width to length is set to at least 1:1 at the spoon volume section. Additionally, in the spoon, the ratio of depth to width is set to less than approximately 1:1.3. The kit accommodates the spoon that is improved based on the human engineering, and a granular detergent substance.
