1. A component for a human-powered vehicle, the component comprising:
a component body;
a strain gauge provided on the component body;
a signal processing unit electrically connected to the strain gauge;
a signal output that outputs a signal from the signal processing unit; and
an electric power input electrically connected to the signal processing unit and supplied with electric power from a power supply provided on at least one of the human-powered vehicle and the component body,
the strain gauge including
a substrate, and
a resistor provided on the substrate, and
the resistor being formed by a metal layer having a thickness of 0.01 micrometers or greater and 1 micrometer or less, the strain gauge including a gauge wire provided on the substrate and electrically connected to the resistor, the gauge wire having a lower electrical resistance per unit length than the resistor.
