  "textContent": "Provided is a catalyst layer for fuel cell which has a high catalytic activity and enables maintaining the high catalytic activity. Disclosed is an electrode catalyst layer for fuel cell including a catalyst containing a catalyst carrier having carbon as a main component and a catalytic metal supported on the catalyst carrier, and a polymer electrolyte having a sulfonic acid group (-SO 3 H) as an ion exchange group, in which the catalyst has the R' (D' /G intensity ratio) of 0.6 or less, which is the ratio of D' band peak intensity (D' intensity) measured in the vicinity of 1620 cm -1 relative to G band peak intensity (G intensity) measured in the vicinity of 1580 cm -1 by Raman spectroscopy, and has BET specific surface area of 900 m 2 /g catalyst carrier or more, and mole number of a sulfonic acid group in the polymer electrolyte relative to weight of the catalyst carrier is 0.7 mmol/g or more and 1.0 mmol/g or less.",
