[0001]

TECHNICAL FIELD The present invention is comfortable to sit on,
The present invention relates to a toilet seat that can be used cleanly.

[0002]

2. Description of the Related Art Conventionally, such toilet seats include, for example,
JP-A-04-338430 and JP-A-05-176
No. 859 was disclosed.

[0003] Further, the toilet seat member often comes into direct contact with the skin, and attention is paid to its hygiene. For this reason, many devices have been put to practical use. In recent years, wiping cloths impregnated with a germicide, toilet seat sheets in which an inorganic antibacterial agent is dispersed, and the like have been partially used.

[0004]

However, in the above-mentioned conventional toilet seat, sitting comfort is emphasized, but various human bodies are apt to be stained depending on use conditions, and bacteria and fungi grow if daily care is neglected. It is easy to smell and may emit a bad smell. In addition, cockroaches and other unpleasant pests caused by inducing substances are likely to become dirty when they enter.

[0005]
