1. A thermoplastic liquid crystal polymer molded body comprising a thermoplastic polymer capable of forming an optically anisotropic melt phase (hereafter referred to as a thermoplastic liquid crystal polymer or TLCP), wherein
the TLCP molded body includes an adherend portion in at least a part of the TLCP molded body, and
the adherend portion has a surface satisfying:
a ratio of <C—O> relative to <COO> (<C—O>/<COO>) of 1.5 or higher and 3.0 or lower in which the <C—O> represents a proportion of a peak area of [C—O bond] based on 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;
a ratio of <C—O> relative to <COO> (<C—O>/<COO>) of 0.10 or higher and 0.70 or lower 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; and
the <C—O> is from 19.0 to 30.0% in a result of X-ray photoelectron spectroscopy analysis of the surface of the adherend portion.
