PROBLEM TO BE SOLVED: To improve strength without increasing the manufacturing cost of a panel 6, in a load conveying carrier wherein the panel 6 arranging vertical muntins 8 and horizontal muntins 9 inside of a peripheral frame 7 in a lattice shape is raised from a side of a loading space portion of the load conveying carrier. SOLUTION: The horizontal muntins 9 is structured to have a glasses-shaped cross section composed of two of upper and lower pipe-shaped parts 9a, 9b and a vertical wall portion 9c connecting both pipe-shaped parts 9a, 9b. The two of the upper and lower pipe-shaped parts 9a, 9b of the horizontal muntins 9 and the vertical muntins 8 are adhered with each other by pressurization electric resistance welding of both intersection abutting portions.
