To provide a hydrogen intrusion monitoring method that has detection sensitivity comparable with a hydrogen permeation method, does not require a strong base solvent, special carrier gas, vacuum environment, etc., and can be used in any measurement environment, and a hydrogen intrusion monitoring device.SOLUTION: A hydrogen intrusion monitoring method comprises the steps of: forming a hydrogen gasification promoting film on a detection surface of a plate-shaped sample with a thickness of 2.0 mm or less; exposing a test surface, which is an opposite surface of the detection surface of the sample, to a test environment; and measuring an amount of gasified hydrogen on the detection surface using hydrogen amount measuring means.SELECTED DRAWING: Figure 2 【課題】水素透過法と同等の検出感度を有し、強塩基の溶媒、特殊なキャリアーガス、及び真空環境等が不要であり、測定環境を選ばない水素侵入モニタリング方法及び水素侵入モニタリング装置を提供する。【解決手段】本発明の一態様に係る水素侵入モニタリング方法は、厚さが２．０ｍｍ以下の板状である試料の検出面に、水素ガス化促進皮膜を形成する工程と、前記試料の前記検出面の反対面である試験面を、試験環境に曝露する工程と、前記検出面においてガス化された水素の量を、水素量測定手段を用いて測定する工程と、を備える。【選択図】図２
