An infrared heating device, comprising: an infrared irradiation means (11,12) that is configured to irradiate infrared rays to an object to be heated to heat the object to be heated; a holding member that holds the infrared irradiation means (11,12); a noncontact temperature measurement means that is attached to the holding member and is configured to measure temperature of a surface of the object to be heated; and at least one pair of laser beam irradiation means (15a-j) that is attached to the holding member and is configured to irradiate laser beams (21a-j) to the surface of the object to be heated from different positions, wherein the at least one pair of laser beam irradiation means (15a-j) is configured to cause the respective laser beams (21a-j) to be coincident in position with each other at one point (P0,P1,P2,P3) on the surface of the object to be heated when a distance between the surface of the object to be heated and the infrared irradiation means (11,12) is a predetermined distance, characterized in that each of the laser beam irradiation means (15a-j) is attached to the holding member while being supported by a support plate (16a-j), and the at least one pair of laser beam irradiation means (15a-j) is attached, through the support plates (16a-j), to both ends of the holding member in a longitudinal direction with the noncontact temperature measurement means as a center, a) so as to be arranged in line symmetry with each other about a measurement direction, or b) so as to be arranged in symmetry with each other with respect to a plane about a plane passing through a measurement direction. an infrared irradiation means (11,12) that is configured to irradiate infrared rays to an object to be heated to heat the object to be heated; a holding member that holds the infrared irradiation means (11,12); a noncontact temperature measurement means that is attached to the holding member and is configured to measure temperature of a surface of the object to be heated; and at least one pair of laser beam irradiation means (15a-j) that is attached to the holding member and is configured to irradiate laser beams (21a-j) to the surface of the object to be heated from different positions, wherein the at least one pair of laser beam irradiation means (15a-j) is configured to cause the respective laser beams (21a-j) to be coincident in position with each other at one point (P0,P1,P2,P3) on the surface of the object to be heated when a distance between the surface of the object to be heated and the infrared irradiation means (11,12) is a predetermined distance, characterized in that each of the laser beam irradiation means (15a-j) is attached to the holding member while being supported by a support plate (16a-j), and the at least one pair of laser beam irradiation means (15a-j) is attached, through the support plates (16a-j), to both ends of the holding member in a longitudinal direction with the noncontact temperature measurement means as a center, a) so as to be arranged in line symmetry with each other about a measurement direction, or b) so as to be arranged in symmetry with each other with respect to a plane about a plane passing through a measurement direction. a) so as to be arranged in line symmetry with each other about a measurement direction, or b) so as to be arranged in symmetry with each other with respect to a plane about a plane passing through a measurement direction.
