Abstract:
A solar-heat collection tube is provided with: a central metal tube through which a heat medium can flow; a glass tube covering the outer periphery of the central metal tube such that a ring-shaped vacuum space is formed between the glass tube and the central metal tube, the glass tube being provided with an endpiece having an end face; and a metal thermal-expansion-difference absorption section for absorbing the thermal expansion difference between the central metal tube and the glass tube. The thermal-expansion-difference absorption section is formed from metal in a ring shape, and has a connection endpiece connected to the endpiece of the glass tube. The connection endpiece is formed so as to gradually decrease in thickness. The connection endpiece is connected to the glass tube in a state of having penetrated into the endpiece of the glass tube from the end face of the glass tube.
