Exhaust Gas Purification Catalyst

An exhaust gas purification catalyst configured to be disposed in an exhaust path of an internal combustion engine and purify an exhaust gas discharged from the internal combustion engine, the exhaust gas purification catalyst comprising:

• a substrate that divides cells through which an exhaust gas flows;
• and
• a catalyst layer that is provided on a surface of the substrate,
• wherein the catalyst layer includes
• a palladium layer containing palladium that extends from a first end part which is an end part on a side of the cells into which an exhaust gas flows to a second end part which is an end part on a side of the cells from which an exhaust gas flows out,
• a platinum layer containing platinum that extends from the second end part to the first end part, and
• a rhodium layer containing rhodium that is laminated with both the palladium layer and the platinum layer.
