The heat sink includes a main plate portion disposed to face the circuit board, and boss portions protruding from the main plate portion toward the circuit board and abutting the circuit board, and is a member fixed to the circuit board by screwing. The heat dissipation grease is a heat transfer material that is interposed between the circuit board and the main plate portion, and has fluidity. The main plate portion includes, on a heat transfer surface facing the circuit board, a first grease application region to which the heat dissipation grease is applied. The circuit board includes a shielding wall extending from a heat dissipation surface facing the main plate portion toward an intermediate region between the first boss portion and the first grease application region in the main plate portion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit device","description":"A circuit device 1 includes: a circuit assembly including a circuit board; a heat sink; and heat dissipation grease.
