A plate heat exchanger, and a heat exchanger plate for the plate heat exchanger for heat exchange between a first fluid and a second fluid are disclosed. The heat exchanger plate comprises a heat exchanger area comprising a first end zone, a central main zone adjoining the first end zone, a second end zone adjoining the central main zone, and a corrugation of ridges and valleys on the heat exchanger area. A longitudinal center axis extends along and through the three zones. The ridges and valleys extend along a respective continuous line, which is at least partly curved and forms an angle of inclination with the longitudinal center axis. The angle of inclination at the longitudinal center axis is less steep for the continuous lines at the first end zone than at the central main zone.
