An infrared welding machine has a heating device that heats and melts at least one of an end surface of a first member made of resin and an end surface of a second member made of resin, called a surface-to-be-heated, with infrared rays. The heating device includes: a lamp that is disposed so as to face the surface-to-be-heated without coming into contact with the surface-to-be-heated and has a circular shape in cross-section such that the lamp radiates infrared rays in all radially outward directions; an upper-side reflective member that reflects infrared rays radiated from the lamp toward the upper side of the surface-to-be-heated so as to direct the infrared rays toward the surface-to-be-heated; and a lower-side reflective member that reflects infrared rays radiated from the lamp toward the lower side of the surface-to-be-heated so as to direct the infrared rays toward the surface-to-be-heated. 红外线熔敷机具有用于通过红外线来将树脂制的第一构件的端面和树脂制的第二构件的端面中的至少任一方(称为加热对象面)加热、熔融的加热装置。加热装置具备：截面圆形的灯，被配置为与所述加热对象面非接触地对置且向径向朝外的全方位辐射红外线
