A solar collector in a vacuum tube is provided to prevent fatal problem of a system even when one or two vacuum pipes are damaged, and to reduce manufacturing cost. A solar collector in a vacuum tube comprises a connecting pipe(100), a sealing cover(200), a connecting pipe insert port(201), an inner collecting pipe(400) with an inner collecting pipe cover thimble(401), and a glass vacuum pipe(300). The connecting pipe is connected with the lower part of the inner collecting pipe through the connecting pipe insert port of the sealing cover. The connecting pipe is attached with the sealing cover. The glass vacuum pipe surrounds the inner colleting pipe cover thimble and attached with the sealing cover. The connecting pipe insert port is drilled to the sealing cover. The solar collector is connected with an inflow/outflow heat media circulation path through the connecting pipe in series or in parallel.
