The invention relates to a method for manufacturing a high-strength titanium alloy golf club head member and a product of the high-strength titanium alloy golf club head member. The method comprises the following steps that: a titanium alloy is used to precast into at least one club head member; the club head member is heated up to over a critical temperature till a martensite is started generating; the temperature of the club head member is maintained over the critical temperature for 30 minutes; the temperature of the club head member is cooled to the room temperature at a cooling speed of over 10 DEG C/s; the club head member is heated up to a heat treatment temperature which is over 450 DEG C; the temperature of the club head member is maintained at the heat treatment temperature for at least one hour; and the club head member is cooled to the room temperature, thereby increasing the mechanical strength of the golf club head.
