Mesoporous carbon has a connecting structure in which primary particles made of carbon particles having primary pores with a primary pore diameter of less than 20 nm are connected. In the mesoporous carbon, the pore capacity of secondary pores with secondary pore diameters within a range of 20 nm to 100 nm, which is measured by a mercury intrusion method, is 0.42 cm/g or more and 1.34 cm/g or less. In addition, the mesoporous carbon has a linearity of 2.2 or more and 2.6 or less. An electrode catalyst for a fuel cell includes the mesoporous carbon and catalyst particles supported in the primary pores in the mesoporous carbon. Furthermore, a catalyst layer includes the electrode catalyst for the fuel cell and a catalyst layer ionomer.

A flavor improver for a polyunsaturated fatty acid-containing fat or oil, containing a basic peptide; and a polyunsaturated fatty acid-containing fat or oil composition, containing a fat or oil containing a polyunsaturated fatty acid having 18 or more carbon atoms and two more double bonds, a basic amino acid and/or a basic peptide, and an emulsifying agent. The flavor improver for a polyunsaturated fatty acid-containing fat or oil and the polyunsaturated fatty acid-containing fat or oil composition of the present invention can suppress the generation of unpleasant taste and flavor from the polyunsaturated fatty acid over a long time period.
