Vehicle lighting device and vehicle lamp

A vehicle lighting device comprising:

• a socket;
• and
• a light-emitting module that is provided on one end side of the socket,
• the light-emitting module including
• a substrate having a wiring pattern;
• a plurality of light-emitting elements that are electrically connected to the wiring pattern and are connected in series to each other;
• and
• a plurality of thermistors that are electrically connected to the wiring pattern and are connected in parallel to each other, and
• the plurality of thermistors connected in parallel to each other being connected in series with the plurality of light-emitting elements connected in series to each other,
• each of the plurality of light-emitting elements being electrically connected to a first pad of the wiring pattern,
• each of the plurality of thermistors being electrically connected to a second pad of the wiring pattern, and
• a shortest distance between the first pad and the second pad being larger than a thickness of the substrate.
