1. An electronic component comprising:
a multilayer body including a plurality of insulating base materials laminated on each other and including a first main surface and a second main surface which are perpendicular or substantially perpendicular to a lamination direction; and
an alignment mark defined by a conductor and provided on one insulating base material among the plurality of insulating base materials; wherein
the multilayer body includes a first layer area located at a side of the first main surface with respect to the alignment mark and a second layer area located at a side of the second main surface with respect to the alignment mark, at least in a region in which the alignment mark is provided as viewed in the lamination direction;
an insulating base material in the first layer area has higher translucency than an insulating base material in the second layer area; and
a cross-sectional shape of the alignment mark in the lamination direction is a trapezoidal shape including a first base at the side of the first main surface and a second base at the side of the second main surface, the first base being longer than the second base, and the first base being substantially a portion of a surface of the one insulating base material on which the alignment mark is provided.
