Abstract: The present disclosure relates to a temperature measurement device, comprising: a housing having, formed therein, a space through which a power line and an optical cable penetrate, wherein the housing extends in one direction in which the power line extends; and a cable winding part which is disposed in the space of the housing and supports the power line penetrating through the housing. The cable winding part is composed of: a column member which is connected to the inner surface of the housing and extends in the space such that the optical cable penetrating through the housing is wound thereon; and a support member for at least partially supporting the outer circumference of the power line penetrating through the housing. Accordingly, a temperature measurement device having a structure that is easy to install on and separate from a power line can be provided.
