Summary: We consider the nonlinear eigenvalue problem $$ -u''(t) = f(\lambda, u(t)), \quad u \mbox{greater than} 0, \quad u(0) = u(1) = 0, $$ where $\lambda > 0$ is a parameter. It is known that under some conditions on $f(\lambda, u)$, the shape of the solutions associated with $\lambda$ is almost `box' when $\lambda \gg 1$. The purpose of this paper is to study precisely the asymptotic shape of the solutions as $\lambda \to \infty$ from a standpoint of $L^1$-framework. To do this, we establish the asymptotic formulas for $L^1$-norm of the solutions as $\lambda \to \infty$.
