Abstract

A circuit module (1) is provided with a circuit board (2), an insulating protective member (3) disposed on the circuit board (2), and a fuse element (4) mounted on the circuit board (2) with the insulating protective member (3) interposed therebetween, wherein: the fuse element (4) is provided with an insulating board (40), and a case (50) covering a surface of the insulating board (40); the case (50) has a through hole (52) in a side surface (51); and the fuse element (4) is disposed inward of an outer periphery of the insulating protective member (3) as seen in a plan view.

Description

technical field [0001] The present invention relates to a circuit module mounted with a fuse element. [0002] This application claims priority based on Japanese Patent Application No. 2019-024470 filed in Japan on February 14, 2019, the contents of which are incorporated herein. Background technique [0003] Currently, fuse elements are used as protection elements for various electric devices equipped with secondary batteries, such as electronic devices such as mobile phones and portable computers, and rechargeable electric devices. As a fuse element, there is known a fuse element that includes a first electrode and a second electrode formed on the surface of an insulating substrate, is connected between the first electrode and the second electrode, and cuts off the space between the first electrode and the second electrode by fusing. A fuse element of the structure of a fusible conductor. In the fuse element having such a structure, when an overcurrent flows through the ...
