The invention provides electronic equipment that cannot lead to large increase of external dimension and ensures further space inside a body frame based on operability ensuring. A keyboard unit (40) of a notebook PC has a plurality of key heads (42) operationally configured above a support plate (41) and a thin membrane configured between the support plate (41) and the key heads (42), a deep side plate part (41b) positioned at the deep of the body frame (10) of the support plate (41) is positioned nearer above than the front side plate part (41) positioned at the front side so that a step shape is formed, and the actuating length of the low-frequency key head (42) configured at the deep side plate part (41b) is more shortened than the actuating length of the high-frequency key head (42H) configured at the front side plate part (41a).
