An electronic component has a circuit board with a main surface, a chip having a sensor facing the main surface, bump electrodes disposed between the main surface and the chip so as to be placed inside of the edges of the chip in a plan view of the main surface, a dam provided between the main surface and the chip so as to extend at least from the edges of the chip to outer positions of the bump electrodes in a plan view of the main surface, and an under-fill material provided at least in a clearance between the dam and the chip. Between the main surface and the sensor, a space is formed in a region enclosed by the bump electrodes in a plan view of the main surface. The under-fill material is disposed outside of the space in a plan view of the main surface.
