Claim:
A method of manufacturing a light source lamp having an arc tube including a light-emitting portion and a pair of sealing portions extending on both sides of the light-emitting portion, a reflector fixed to one sealing portion to reflect an emission light emitted from the light-emitting portion, and an auxiliary mirror fixed to the other sealing portion to reflect an emission light emitted from the light-emitting portion toward the reflector, the method comprising: setting a light-reflecting surface of the auxiliary mirror so as to face the light-emitting portion and injecting an adhesive into a gap between the auxiliary mirror and the other sealing portion; heating and curing the adhesive from a side nearer to the light-emitting portion of the arc tube so that the vapor and adhesive particles from the adhesive are scattered in a direction opposite to the light-emitting portion; and attaching the reflector to the arc tube with the auxiliary mirror fixed thereto.
