A plate-stacked heat exchanger is proposed which exchanges heat with high heat exchange efficiency in flow paths each including an internal space bulging outward between two heat transfer plates. A flow path forming portion includes a plurality of flow path bulging portions that bulges outward of a heat exchanger plate and forms heat exchange flow paths of a first heating medium therein, and a header portion includes a communication hole communicating with the header portion of an adjacent heat exchanger plate, and a flow path forming portion-side expanded portion expanding from the communication hole toward the flow path forming portion, and the flow path forming portion-side expanded portion communicates with the plurality of heat exchange flow paths. Consequently, heat can be exchanged in a greater width. Therefore, a high heat exchange rate can be obtained.
