Mounting structure of temperature sensor

A mounting structure of a temperature sensor configured to detect temperature of a battery cell included in a battery pack having a plurality of battery cells being connected by mounting on the battery cell, the mounting structure comprises:

• a flexible thin plate-like electric wire including a conductor exposed part where a conductor is exposed;
• a chip-shaped temperature measuring component having a first surface, mounted on and directly facing the conductor exposed part, and a second surface that is opposite to the first surface and facing away from the conductor exposed part;
• a resin case arranged on a periphery of the conductor exposed part and surrounding the temperature measuring component;
• and
• a moisture-proof material coating the temperature measuring component arranged in the resin case;
• a resin material arranged directly on the moisture-proof material arranged in the resin case;
• and
• one or more elastic members,
• wherein the resin case comprises a plurality of projections projected, in a direction in which the second surface is facing, away from the temperature measuring component and onto which the one or more elastic members bias, in a direction from the first surface to the second surface, the resin case towards the temperature measuring component.
