Abstract: An induction heating device includes: a case; working coils; a base plate that supports the working coils; light guides that are installed on the base plate and that cover outer portions of each working coil; light emitting elements disposed below the light guides and configured to emit light; and an indicator substrate that is disposed below the base plate and that seats the light emitting elements. The indicator substrate includes a first indicator substrate, where a first portion of the light emitting elements are arranged along outer portions of the first indicator substrate, and a second indicator substrate disposed at a rear side of the first indicator substrate, where a second portion of the light emitting elements are arranged along outer portions of the second indicator substrate except for an outer portion at a front side that is adjacent to and faces the rear side of the first indicator substrate.
