To provide a manufacturing method of a heat transfer plate that includes high heat-exchange efficiency and is easily manufactured even if a heat medium pipe bent at least in part is included.
The method includes: a preparatory step in which a first recessed groove 5 formed in a first metallic member 2 is superposed on a second recessed groove 6 formed in a second metallic member 3 and in which a heat medium pipe 4 is inserted in a space K formed between the recessed grooves mutually; and an inflow stirring step in which an inflow stirring rotary tool 25 is moved along the space K, wherein the inflow stirring rotary tool is inserted at least from one face of the front and the rear face of a temporary assembled structure U formed in the preparatory step, and in which a plastic fluidized material Q fluidized by a frictional heat is made to flow in voids P1-P4 formed around the heat medium pipe 4. The heat transfer plate is characterized in that at least either the width or the height of the space K is larger than the outer diameter of the heat medium pipe 4.
