To automatically and properly measure the porosity.SOLUTION: A porosity measurement device includes an acquiring unit that acquires an image including a target of porosity measurement, an extracting unit that extracts an image of an area to be a target of porosity measurement from the image, and a calculation unit that calculates the porosity of the measurement target by using a machine-learned machine-learning model that has been machine-learned by setting a feature amount of the image of the area as an explanatory variable, setting the porosity as an objective variable, and setting a plurality of area images to each of which the porosity is attached as teacher data.SELECTED DRAWING: Figure 1 【課題】気孔率を適切に自動で計測する。【解決手段】気孔率計測装置は、気孔率の計測対象を含む画像を取得する取得部と、画像から気孔率の計測対象となる領域画像を抽出する抽出部と、領域画像の特徴量を説明変数とし、かつ、気孔率を目的変数とし、気孔率がそれぞれ付与された複数の領域画像を教師データとして機械学習された学習済み機械学習モデルを用いて、計測対象の気孔率を算出する算出部と、を備える。【選択図】図１
