1. A solar array wing comprising:
an extension mast to be extended from a wound state; and
a support member, around which the extension mast is wound, to support the extension mast after the extension mast is extended, wherein
the support member is made of a fiber reinforced composite material,
a coefficient of linear expansion of the fiber reinforced composite material, a unit of which is for each degree Celsius, in a direction that is orthogonal to an extension direction of the extension mast, is higher than or equal to −1×10−6 and lower than or equal to 1×10−6,
the extension mast is made of carbon fiber reinforced plastic, and
in the fiber reinforced composite material of the support member, a matrix having a melting point below a glass-transition temperature of the carbon fiber reinforced plastic of the extension mast is used.
