# レスポンスモデル

*path operations* のいずれにおいても、`response_model`パラメータを使用して、レスポンスのモデルを宣言することができます:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* など。

```Python hl_lines="17"
{!../../docs_src/response_model/tutorial001.py!}
```

/// note | "備考"

`response_model`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数* のパラメータではありません。
