An electronic component module includes: an insulative substrate; a device chip mounted on a first surface of the insulative substrate in flip-chip mounting; a chip component connected to the insulative substrate; a lid provided above the insulative substrate and the device chip; a first metal pattern that is provided in edge portions on the first surface of the insulative substrate so as to surround the first surface of the insulative substrate; a second metal pattern that is provided in edge portions on a second surface of the lid opposite to the first surface so as to surround the second surface; and seal solder joining the first and second metal patterns so as to define a cavity that is formed in a region that is located between the insulative substrate and the lid and is not provided with the first and second metal patterns and is further formed between the insulative substrate and the device chip.
