The core existence theorem of an NTU (non-transferable utility) game that there exists a core in a balanced game, which was first presented by Scarf (Econometrica, 1967), is usually proved by means of proofs based on Kakutani's fixed point theorem such as Shapley (Mathematical Programming edited by Hu et al., Academic Press, 1973) and Shapley and Vohra (Economic Theory, 1991). On the other hand, in this paper, we present a proof of this theorem by means of Brouwer's fixed point theorem (which is more elementary than Kakutani's theorem) by unifying the two-stage proof by Zhou (Economic Theory, 1994).
