Abstract

Provided is a ceramic package for filling a liquid-component containing electrolyte, the package making corrosion caused by the electrolyte less susceptible to progressing to the outside of a cavity even if the electrolyte is filled inside the cavity. A ceramic package 1a for filling a liquid-component containing electrolyte comprises: a substrate body 2 that is made of ceramic and has front and rear surfaces 3, 4 and a side surface 5 positioned therebetween; a cavity 6 that opens to the surface 3 and has a bottom surface 7 and an inner side surface 8; an electrode pad 9 formed on the bottom surface 7; an external connection terminal 10 formed on the rear surface 4; an electronic component 14 mounted on the electrode pad 9; and an electrolyte 16 which is filled into the cavity 6. The electrode pad 9 and the external connection terminal 10 are electrically connected by a via conductor 12 that goes through a ceramic layer c1 forming the bottom surface 7 of the cavity 6 and the rear surface 4 of the substrate body 2. The side surface 5 of the substrate body 2 has a side surface conductor 17, and the side surface conductor 17 and the external connection terminal 10 are connected, and the electrode pad 9 and the side surface conductor 17 are disposed so as to be separated from each other.

Description

technical field [0001] The present invention relates to a ceramic package for filling an electrolyte containing a liquid component, which is used for filling a gel-like electrolyte containing a liquid component, such as a gel, into a cavity opened on the surface of a substrate main body made of ceramics, and surrounding the cavity with the electrolyte. The electronic components are then mounted within the chamber. Background technique [0002] For example, for a ceramic package in which a cavity opened above is formed by laminating a ceramic frame on the peripheral side of the upper surface of a flat ceramic substrate, there is proposed an arc-shaped notch and a round-castle-shaped conductor (Japanese: The arc-shaped notch portion is a ceramic package of a caster-shaped conductor), wherein at least one arc-shaped corner portion of the chamber (an arc-shaped inner corner portion in a plan view) is cut away toward the outer peripheral side in a plan view. The dome-shaped cond...
