Title: Loop antenna and loop antenna manufacturing method

Abstract: A loop antenna is disclosed which can prevent the occurrence of variance in the loop length of the installed loop antenna element, and a method for manufacturing the loop antenna. The loop antenna comprises electrical wires constituting the antenna element and a housing that holds the electrical wires. Furthermore, the housing is formed with first guide grooves that guide the first end portions of the electrical wires and that have wall surfaces against which the tip ends on the side of the first end portions of the electrical wires abut, and second guide grooves that guide the second end portions of the electrical wires and that have wall surfaces against which the tip ends on the side of the second end portions of the electrical wires abut. Moreover, crimp parts with which the end portions of the electrical wires are connected by crimping are provided inside the respective guide grooves. In addition, a pair of contact parts that make contact with external terminals are respectively connected to the crimp parts.
