Abstract

A thermoplastic liquid crystal polymer (TLCP) molded body including a thermoplastic polymer capable of forming an optically anisotropic melt phase. The TLCP molded body includes an adherend portion in at least a part of the TLCP molded body. The adherend portion has a surface satisfying: a ratio <C—O>/<COO> of 1.5 or greater in which the <C—O> represents a proportion of a peak area of [C—O bond] to a C(1s) peak area, and the <COO> represents a proportion of a peak area of [COO bond] based on the C(1s) peak area; and a ratio <C═O>/<COO> of 0.10 or higher in which the <C═O> represents a proportion of a peak area of [C═O bond] based on the C(1s) peak area, and the <COO> represents the proportion of the peak area of the [COO bond] based on the C(1s) peak area in a result of X-ray photoelectron spectroscopy analysis.
