Integration, chapter VI, § 1. Integration of vector-valued functions

Suppose F is semi-reflexive, and let f be a scalarly essentially μ\mu-integrable mapping of T into F such that, for every compact subset K of T, f(K)f(K) is bounded. Then ∫fdμ\int f d\mu belongs to F.

For, every bounded subset of F is relatively weakly compact (TVS, IV, §2, No. 2, Th. 1), and F=F′′F = F''.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
