Provided is a rotation angle detection device including: an intermediate signal generation unit configured to generate an intermediate signal based on a product of a sine signal and a cosine signal which are based on a rotation angle of a rotating body; a first multiplication unit; and a first rotation angle calculation unit. The intermediate signal generation unit includes: a first multiplier configured to calculate the product of the sine signal and the cosine signal; and a first low-pass filter configured to remove frequency components equal to or higher than twice a frequency of fundamental waves of the sine signal and the cosine signal from an output of the first multiplier.
