Provided are a cooling device and an electric vehicle using the cooling device. The cooling device (10) is used for cooling a switching module (98) containing a switching element as a heating element. The cooling device (10) includes a cooling liquid channel (102) having a plurality of cooling fins (120) through which the cooling liquid flows. The cooling fins (120) have a cut-off portion (118) at the position corresponding at least to a center portion of chips (91, 92) constituting the switching module (98) in the flow direction of the cooling liquid. A chamber (122) is formed in the cooling liquid channel (102) by the cut-off portion (118). |
