Wiring unit, magnetic sensor unit, and method of manufacturing wiring unit

A method of manufacturing a wiring unit in which a plurality of terminals including at least a first terminal and a second terminal are resin-molded, the method of manufacturing the wiring unit comprising the steps of:

• locking a first notch portion provided in a first extended portion extending in a first direction in the first terminal to a first locking portion of a protrusion provided in a first mold and fixing the first notch portion to the first mold;
• locking a second notch portion provided in a second extended portion extending in the first direction in the second terminal to a second locking portion provided on a side of an end portion of the protrusion relative to the first locking portion in the protrusion and fixing the second notch portion to the first mold such that at least a part of the first extended portion and at least a part of the second extended portion face each other while being spaced apart in a second direction perpendicular to the first direction;
• and
• filling resin into an internal space formed by the first mold and other molds including a second mold.
